外设 I/O 上的回路功能
TMS570LS3137-EP 器件集成了 ARM Cortex-R4F 浮点 CPU,此 CPU 可提供一个高效的 1.66
DMIPS/MHz,并且 具有能够以高达 180 MHz 运行的配置,从而提供高达 298 DMIPS。 此器件支持字不变
大端序 [BE32] 格式。
TMS570LS3137-EP 器件具有 3MB 的集成闪存以及 256KB 的数据 RAM,这些闪存和 RAM 支持单位错误
校正和双位错误检测。 这个器件上的闪存存储器是一个由 64 位宽数据总线接口实现的非易失性、电可擦除
并且可编程的存储器。 为了实现所有读取、编程和擦除操作,此闪存运行在一个 3.3V 电源输入上(与 I/O
电源一样的电平)。 当处于管线模式中时,闪存可在高达 180MHz 的系统时钟频率下运行。 在字节、半
字、字和双字模式中,SRAM 支持单循环读取和写入访问。
TMS570LS3137-EP 器件特有针对基于实时控制应用的外设,其中包括 2 个下一代高端定时器 (N2HET) 时
序协处理器和 2 个支持多达 24 个输入的 12 位模数转换器 (ADC) 。
N2HET1 是一款高级智能定时器,此定时器能够为实时应用提供精密的计时功能。 该定时器为软件控制
型,采用一个精简指令集,并具有一个专用的定时器微级机和一个连接的 I/O 端口。 N2HET 可被用于脉宽
调制输出,捕捉或比较输入,GPIO。 N2HET 特别适合于要求多个传感器信息并且用复杂和准确时间脉冲来
驱动致动器的应用。 一个高端定时器传输单元 (HTU) 能够执行 DMA 类型处理来与主存储器之间传输
N2HET 数据。 一个内存保护单元 (MPU) 被内置于 HTU 内。
此器件具有 2 个 12 位分辨率 MibADC,每个 MibADC 具有 24 个通道和受 64 字奇偶校验保护的缓冲器
RAM。 MibADC 通道可被独立转换或者可针对顺序转换序列由软件成组。 16 个通道可在两个 MibADC 间
共用。 有三个独立的组。 当被触发或者针对连续转换模式进行配置后,每个序列可被转换一次。
此器件有多个通信接口:3 个 MibSPI,,1 个 LIN,1 个SCI,3 个 DACN,1 个 I2C。 SPI 为相似移位寄存
器类型器件之间串行高速通信的提供了一个便捷方法。 LIN 支持本地互联标准 2.0 并可被用作一个使用标准
不归零码 (NRZ) 格式的全双工模式 UART。
DCAN 支持 CAN 2.0(A 和 B)协议标准并使用一个串行、多主控通信协议,此协议用高达 1Mbps 的稳健
耐用通信速率有效支持分布式实时控制。 DCAN 非常适合于工作于嘈杂和恶劣环境中的系统(例如,汽车
网络互连和工业领域),此类系统需要可靠的串行通信或多路复用布线。
I2C 模块是一个多主控通信模块,此模块通过 I2C 串行总线在微控制器和一个 I2C 兼容器件之间提供一个接
口。 此 I2C 支持 100Kbps 和 400Kbps 的速度。

ZHCSBS0C –OCTOBER 2013–REVISED JANUARY 2015
此器件还有一个外部时钟前置分频器 (ECP) 模块,当被启用时,此模块在 ECLK 引脚/焊球上输出一个连续
外部时钟。 ECLK 频率是一个外设接口时钟 (VCLK) 频率的用户可编程比例。 这个可被外部监视的低频输出
作为此器件运行频率的指示器。
直接内存访问 (DMA) 控制器有 16 个通道,32 个控制数据包和针对其内存的奇偶校验保护。 在 DMA 中内
置了一个 MPU 来将 DMA 限制在存储器的指定区域,并且保护存储器系统的剩余部分不受 DMA 故障的影
响。
错误信令模块 (ESM) 监控所有器件错误并在检测到一个故障时确定是生成一个中断还是触发一个外部
ERROR 引脚。 可从外部监视此 ERROR 引脚,将其作为一个微控制器内故障条件的指示器。
外部存储器接口 (EMIF) 提供芯片外扩展功能,此功能可实现与同步 DRAM (SDRAM) 器件、异步存储器、
外设或现场可编程门阵列 (FPGA) 器件的对接。
执行几个接口来提高应用代码的调试能力。 除了内置的 ARM Cortex-R4F CoreSight 调试特性,一个外部跟
踪宏单元 (ETM) 提供程序执行的指令和数据跟踪。 为了实现仪器测量的目的,执行了一个 RAM 跟踪端口
模块 (RTP) 来支持由 CPU 或者任何其它主控所访问的 RAM 和外设的高速跟踪。 一个数据修改模块
(DMM) 提供向器件内存写入外部数据的功能。 RTP 和 DMM 对于应用代码的程序执行时间没有影响或者只
有很小的影响。 一个参数覆盖模块 (POM) 可将闪存访问重新路由至内部存储器或 EMIF。 这个重新路由可
对照生产代码对参数和表格进行动态校准,而无需重建代码以明确访问 RAM 或停止处理器来重新编辑数据
闪存。
借助集成的安全特性和通信与控制外设的广泛选择, 器件是针对具有安全关键要求的高性能实时控制应用的
理想解决方案。

4.1.1 Pin Attributes
4.1.1.1 identifies the external signal names, the associated pin/ball numbers along with the mechanical
package designator, the pin/ball type (Input, Output, IO, Power or Ground), whether the pin/ball has any
internal pullup/pulldown, whether the pin/ball can be configured as a GPIO, and a functional pin/ball
description. The first signal name listed is the primary function for that terminal. The signal name in Bold is
the function being described. Refer to the TMS570LS31X/21X Technical Reference Manual (SPNU499)
for information on how to select between different multiplexed functions.
NOTE
All I/O signals except nRST are configured as inputs while nPORRST is low and immediately
after nPORRST goes High.
All output-only signals are configured as inputs while nPORRST is low, and are
configured as outputs immediately after nPORRST goes High.
While nPORRST is low, the input buffers are disabled, and the output buffers are
tri-stated.
In the Pin Functions table below, the "Default Pull State" is the state of the pullup or
pulldown while nPORRST is low and immediately after nPORRST goes High. The
default pull direction may change when software configures the pin for an alternate
function. The "Pull Type" is the type of pull asserted when the signal name in bold
is enabled for the given pin.

As shown in the figure above, the TCM RAM can support program and data fetches at full CPU speed without any address or data wait
states required.
The TCM flash can support zero address and data wait states up to a CPU speed of 50 MHz in non-pipelined mode. The flash supports a
maximum CPU clock speed of 180MHz for the GWT package, with one address wait state and three data wait states.
The flash wrapper defaults to non-pipelined mode with zero address wait state and one random-read data wait state.

ZHCSBS0C –OCTOBER 2013–REVISED JANUARY 2015
5.13 Low-EMI Output Buffers
The low-EMI output buffer has been designed explicitly to address the issue of decoupling sources of
emissions from the pins which they drive. This is accomplished by adaptively controlling the impedance of
the output buffer, and is particularly effective with capacitive loads.
This is not the default mode of operation of the low-EMI output buffers and must be enabled by setting the
system module GPCR1 register for the desired module or signal, as shown in 表 5-8. The adaptive
impedance control circuit monitors the DC bias point of the output signal. The buffer internally generates
two reference levels, VREFLOW and VREFHIGH, which are set to approximately 10% and 90% of
VCCIO, respectively.
Once the output buffer has driven the output to a low level, if the output voltage is below VREFLOW, then
the output buffer’s impedance will increase to hi-Z. A high degree of decoupling between the internal
ground bus and the output pin will occur with capacitive loads, or any load in which no current is flowing,
e.g. the buffer is driving low on a resistive path to ground. Current loads on the buffer which attempt to pull
the output voltage above VREFLOW will be opposed by the buffer’s output impedance so as to maintain
the output voltage at or below VREFLOW.
Conversely, once the output buffer has driven the output to a high level, if the output voltage is above
VREFHIGH then the output buffer’s impedance will again increase to hi-Z. A high degree of decoupling
between internal power bus ad output pin will occur with capacitive loads or any loads in which no current
is flowing, e.g. buffer is driving high on a resistive path to VCCIO. Current loads on the buffer which
attempt to pull the output voltage below VREFHIGH will be opposed by the buffer’s output impedance so
as to maintain the output voltage at or above VREFHIGH.
The bandwidth of the control circuitry is relatively low, so that the output buffer in adaptive impedance
control mode cannot respond to high-frequency noise coupling into the buffer’s power buses. In this
manner, internal bus noise approaching 20% peak-to-peak of VCCIO can be rejected.
Unlike standard output buffers which clamp to the rails, an output buffer in impedance control mode will
allow a positive current load to pull the output voltage up to VCCIO + 0.6V without opposition. Also, a
negative current load will pull the output voltage down to VSSIO – 0.6V without opposition. This is not an
issue since the actual clamp current capability is always greater than the IOH / IOL specifications.
The low-EMI output buffers are automatically configured to be in the standard buffer mode when the
device enters a low-power mode.

6 System Information and Electrical Specifications
6.1 Device Power Domains
The device core logic is split up into multiple power domains in order to optimize the power for a given
application use case. There are 8 core power domains in total: PD1, PD2, PD3, PD4, PD5, RAM_PD1,
RAM_PD2, and RAM_PD3.
The actual contents of these power domains are indicated in 节 1.4.
PD1 is an "always-ON" power domain, which cannot be turned off. Each of the other core power domains
can be turned ON/OFF one time during device initialization as per the application requirement. Refer to
the Power Management Module (PMM) chapter of TMS570LS31X/21X Technical Reference Manual
(SPNU499) for more details.
注
The clocks to a module must be turned off before powering down the core domain that
contains the module.
注
The logic in the modules that are powered down lose power completely. Any access to
modules that are powered down results in an abort being generated. When power is
restored, the modules power-up to their default states (after normal power-up). No register or
memory contents are preserved in the core domains that are turned off.

ZHCSBS0C –OCTOBER 2013–REVISED JANUARY 2015
6.2 Voltage Monitor Characteristics
A voltage monitor is implemented on this device. The purpose of this voltage monitor is to eliminate the
requirement for a specific sequence when powering up the core and I/O voltage supplies.
6.2.1 Important Considerations
•
The voltage monitor does not eliminate the need of a voltage supervisor circuit to ensure that the
device is held in reset when the voltage supplies are out of range.
•
The voltage monitor only monitors the core supply (VCC) and the I/O supply (VCCIO). The other
supplies are not monitored by the VMON. For example, if the VCCAD or VCCP are supplied from a
source different from that for VCCIO, then there is no internal voltage monitor for the VCCAD and
VCCP supplies.
6.2.2 Voltage Monitor Operation
The voltage monitor generates the Power Good MCU signal (PGMCU) as well as the I/Os Power Good IO
signal (PGIO) on the device. During power-up or power-down, the PGMCU and PGIO are driven low when
the core or I/O supplies are lower than the specified minimum monitoring thresholds. The PGIO and
PGMCU being low isolates the core logic as well as the I/O controls during the power-up or power-down
of the supplies. This allows the core and I/O supplies to be powered up or down in any order.
When the voltage monitor detects a low voltage on the I/O supply, it will assert a power-on reset. When
the voltage monitor detects an out-of-range voltage on the core supply, it asynchronously makes all output
pins high impedance, and asserts a power-on reset. The voltage monitor is disabled when the device
enters a low power mode.
The VMON also incorporates a glitch filter for the nPORRST input. Refer to 节 6.3.3.1 for the timing
information on this glitch filter.

6.3 Power Sequencing and Power On Reset
6.3.1 Power-Up Sequence
There is no timing dependency between the ramp of the VCCIO and the VCC supply voltage. The power-
up sequence starts with the I/O voltage rising above the minimum I/O supply threshold, (see 表 6-4 for
more details), core voltage rising above the minimum core supply threshold and the release of power-on
reset. The high frequency oscillator will start up first and its amplitude will grow to an acceptable level. The
oscillator start up time is dependent on the type of oscillator and is provided by the oscillator vendor. The
different supplies to the device can be powered up in any order.
The device goes through the following sequential phases during power up.

6.4 Warm Reset (nRST)
This is a bidirectional reset signal. The internal circuitry drives the signal low on detecting any device reset
condition. An external circuit can assert a device reset by forcing the signal low. On this terminal, the
output buffer is implemented as an open drain (drives low only). To ensure an external reset is not
arbitrarily generated, TI recommends that an external pullup resistor is connected to this terminal.
This terminal has a glitch filter. It also has an internal pullup

6.6.1.1 Main Oscillator
The oscillator is enabled by connecting the appropriate fundamental resonator/crystal and load capacitors
across the external OSCIN and OSCOUT pins as shown in 图 6-4. The oscillator is a single stage inverter
held in bias by an integrated bias resistor. This resistor is disabled during leakage test measurement and
low power modes.
TI strongly encourages each customer to submit samples of the device to the resonator/crystal
vendors for validation. The vendors are equipped to determine what load capacitors will best tune
their resonator/crystal to the microcontroller device for optimum start-up and operation over
temperature/voltage extremes.
An external oscillator source can be used by connecting a 3.3V clock signal to the OSCIN pin and leaving
the OSCOUT pin unconnected (open) as shown in the figure below.

6.6.3 Clock Test Mode
The TMS570 platform architecture defines a special mode that allows various clock signals to be brought
out on to the ECLK pin and N2HET1[12] device outputs. This mode is called the Clock Test mode. It is
very useful for debugging purposes and can be configured via the CLKTEST register in the system
module.

6.7 Clock Monitoring
The LPO Clock Detect (LPOCLKDET) module consists of a clock monitor (CLKDET) and an internal low
power oscillator (LPO).
The LPO provides two different clock sources – a low frequency (CLK80K) and a high frequency
(CLK10M).
The CLKDET is a supervisor circuit for an externally supplied clock signal (OSCIN). In case the OSCIN
frequency falls out of a frequency window, the CLKDET flags this condition in the global status register
(GLBSTAT bit 0: OSC FAIL) and switches all clock domains sourced by OSCIN to the CLK10M clock (limp
mode clock).
The valid OSCIN frequency range is defined as: fCLK10M / 4 < fOSCIN < fCLK10M * 4.

6.7.2 External Clock (ECLK) Output Functionality
The ECLK pin can be configured to output a pre-scaled clock signal indicative of an internal device clock.
This output can be externally monitored as a safety diagnostic.
6.7.3 Dual Clock Comparators
The Dual Clock Comparator (DCC) module determines the accuracy of selectable clock sources by
counting the pulses of two independent clock sources (counter 0 and counter 1). If one clock is out of
spec, an error signal is generated. For example, the DCC1 can be configured to use CLK10M as the
reference clock (for counter 0) and VCLK as the "clock under test" (for counter 1). This configuration
allows the DCC1 to monitor the PLL output clock when VCLK is using the PLL output as its source.

ZHCSBS0C –OCTOBER 2013–REVISED JANUARY 2015
An additional use of this module is to measure the frequency of a selectable clock source, using the input
clock as a reference, by counting the pulses of two independent clock sources. Counter 0 generates a
fixed-width counting window after a preprogrammed number of pulses. Counter 1 generates a fixed-width
pulse (1 cycle) after a pre-programmed number of pulses. This pulse sets as an error signal if counter 1
does not reach 0 within the counting window generated by counter 0.
6.7.3.1 Features
Takes two different clock sources as input to two independent counter blocks.
•
•
One of the clock sources is the known-good, or reference clock; the second clock source is the "clock
under test."
•
•
Each counter block is programmable with initial, or seed values.
The counter blocks start counting down from their seed values at the same time; a mismatch from the
expected frequency for the clock under test generates an error signal which is used to interrupt the
CPU.

6.9.3.1 Special Notes on Accesses to Certain Slaves
Write accesses to the Power Domain Management Module (PMM) control registers are limited to the CPU
(master id = 1). The other masters can only read from these registers.
A debugger can also write to the PMM registers. The master-id check is disabled in debug mode.
The device contains dedicated logic to generate a bus error response on any access to a module that is in
a power domain that has been turned OFF.

6.9.4 POM Overlay Considerations
•
The POM overlay can map onto up to 8MB of the internal or external memory space. The starting
address and the size of the memory overlay are configurable via the POM module control registers.
Care must be taken to ensure that the overlay is mapped on to available memory.
•
•
•
ECC must be disabled by software via CP15 in case POM overlay is enabled; otherwise ECC errors
will be generated.
POM overlay must not be enabled when the flash and internal RAM memories are swapped via the
MEM SWAP field of the Bus Matrix Module Control Register 1 (BMMCR1).
When POM is used to overlay the flash onto internal or external RAM, there is a bus contention
possibility when another master accesses the TCM flash. This results in a system hang.
–
–
–
The POM module implements a timeout feature to detect this exact scenario. The timeout needs to
be enabled whenever POM overlay is enabled.
The timeout can be enabled by writing 1010 to the Enable TimeOut (ETO) field of the POM Global
Control register (POMGLBCTRL, address = 0xFFA04000).
In case a read request by the POM cannot be completed within 32 HCLK cycles, the timeout (TO)
flag is set in the POM Flag register (POMFLG, address = 0xFFA0400C). Also, an abort is
generated to the CPU. This can be a prefetch abort for an instruction fetch or a data abort for a
data fetch.
–
The prefetch- and data-abort handlers must be modified to check if the TO flag in the POM module
is set. If so, then the application can assume that the timeout is caused by a bus contention
between the POM transaction and another master accessing the same memory region. The abort
handlers need to clear the TO flag, so that any further aborts are not misinterpreted as having been
caused due to a timeout from the POM.

6.10 Flash Memory
6.10.1 Flash Memory Configuration
Flash Bank: A separate block of logic consisting of 1 to 16 sectors. Each flash bank normally has a
customer-OTP and a TI-OTP area. These flash sectors share input/output buffers, data paths, sense
amplifiers, and control logic.
Flash Sector: A contiguous region of flash memory which must be erased simultaneously due to physical
construction constraints.
Flash Pump: A charge pump which generates all the voltages required for reading, programming, or
erasing the flash banks.
Flash Module: Interface circuitry required between the host CPU and the flash banks and pump module.

6.10.2 Main Features of Flash Module
•
•
•
•
•
•
Support for multiple flash banks for program and/or data storage
Simultaneous read access on a bank while performing program or erase operation on any other bank
Integrated state machines to automate flash erase and program operations

•
Support for a rich set of diagnostic features
6.10.3 ECC Protection for Flash Accesses
All accesses to the program flash memory are protected by Single Error Correction Double Error Detection
(SECDED) logic embedded inside the CPU. The flash module provides 8 bits of ECC code for 64 bits of
instructions or data fetched from the flash memory. The CPU calculates the expected ECC code based on
the 64 bits received and compares it with the ECC code returned by the flash module. A signle-bit error is
corrected and flagged by the CPU, while a multi-bit error is only flagged. The CPU signals an ECC error
via its Event bus. This signaling mechanism is not enabled by default and must be enabled by setting the
"X" bit of the Performance Monitor Control Register, c9.

;Enabling Event monitor states
;Set 4th bit (‘X’) of PMNC register
The application must also explicitly enable the CPU's ECC checking for accesses on the CPU's ATCM
and BTCM interfaces. These are connected to the program flash and data RAM respectively. ECC
checking for these interfaces can be done by setting the B1TCMPCEN, B0TCMPCEN and ATCMPCEN
bits of the System Control coprocessor's Auxiliary Control Register, c1.

6.11.1 Features
The features of the Tightly Coupled RAM (TCRAM) Module are:
•
•
•
•
•
•
•
•
Acts as slave to the Cortex-R4F CPU's BTCM interface
Supports CPU's internal ECC scheme by providing 64-bit data and 8-bit ECC code
Monitors CPU Event Bus and generates single or multi-bit error interrupts
Stores addresses for single and multi-bit errors
Supports RAM trace module
Provides CPU address bus integrity checking by supporting parity checking on the address bus
Performs redundant address decoding for the RAM bank chip select and ECC select generation logic
Provides enhanced safety for the RAM addressing by implementing two 36-bit wide byte-interleaved
RAM banks and generating independent RAM access control signals to the two banks
•
•
Supports auto-initialization of the RAM banks along with the ECC bits
No support for bit-wise RAM accesses
6.11.2 TCRAMW ECC Support
The TCRAMW passes on the ECC code for each data read by the Cortex-R4F CPU from the RAM. It also
stores the CPU's ECC port contents in the ECC RAM when the CPU does a write to the RAM. The
TCRAMW monitors the CPU's event bus and provides registers for indicating single/multi-bit errors and
also for identifying the address that caused the single or multi-bit error. The event signaling and the ECC
checking for the RAM accesses must be enabled inside the CPU.
For more information see the device specific technical reference manual.
6.12 Parity Protection for Peripheral RAMs
Most peripheral RAMs are protected by odd/even parity checking. During a read access the parity is
calculated based on the data read from the peripheral RAM and compared with the good parity value
stored in the parity RAM for that peripheral. If any word fails the parity check, the module generates a
parity error signal that is mapped to the Error Signaling Module. The module also captures the peripheral
RAM address that caused the parity error.

The parity protection for peripheral RAMs is not enabled by default and must be enabled by the
application. Each individual peripheral contains control registers to enable the parity protection for
accesses to its RAM.
注
The CPU read access gets the actual data from the peripheral. The application can choose
to generate an interrupt whenever a peripheral RAM parity error is detected.

(1) There are several memory testing algorithms stored in the PBIST ROM. However, TI recommends the March13N algorithm for
application testing.
The PBIST ROM clock frequency is limited to 90MHz, if 90MHz < HCLK ≤ HCLKmax, or HCLK, if HCLK ≤
90MHz.
The PBIST ROM clock is divided down from HCLK. The divider is selected by programming the ROM_DIV
field of the Memory Self-Test Global Control Register (MSTGCR) at address 0xFFFFFF58.

6.13.2 On-Chip SRAM Auto Initialization
This microcontroller allows some of the on-chip memories to be initialized to zero via the Memory
Hardware Initialization mechanism in the System module. This hardware mechanism allows an application
to program the memory arrays with error detection capability to a known state based on their error
detection scheme (odd/even parity or ECC).
The MINITGCR register enables the memory initialization sequence, and the MSINENA register selects
the memories that are to be initialized.
For more information on these registers see the device specific technical reference manual.
The mapping of the different on-chip memories to the specific bits of the MSINENA registers is shown in
表 6-27.

(1) The TCM RAM wrapper has separate control bits to select the RAM power domain that is to be auto-initialized.
(2) The MibSPIx modules perform an initialization of the transmit and receive RAMs as soon as the module is released from its local reset
via the SPIGCR0 register. This is independent of whether the application chooses to initialize the MibSPIx RAMs using the system
module auto-initialization method. Before the MibSPI RAM can be initialized using the system module auto-initialization method: (i) The
module must be released from its local reset, AND (ii) The application must poll for the "BUF INIT ACTIVE" status flag in the SPIFLG
register to become cleared (zero)
(3) Reserved only. The FlexRay RAM has its own initialization mechanism.

wait states. Figure 图 6-12 and Figure 图 6-14 describe EMIF transactions that include extended wait states inserted during the
STROBE phase. However, cycles inserted as part of this extended wait period should not be counted; the 4E requirement is to the start
of where the HOLD phase would begin if there were no extended wait cycles.

6.15 Vectored Interrupt Manager
The vectored interrupt manager (VIM) provides hardware assistance for prioritizing and controlling the
many interrupt sources present on this device. Interrupts are caused by events outside of the normal flow
of program execution. Normally, these events require a timely response from the central processing unit
(CPU); therefore, when an interrupt occurs, the CPU switches execution from the normal program flow to
an interrupt service routine (ISR).
6.15.1 VIM Features
The VIM module has the following features:
•
Supports 96 interrupt channels.
Provides programmable priority and enable for interrupt request lines.
–
•
•
Provides a direct hardware dispatch mechanism for fastest IRQ dispatch.
Provides two software dispatch mechanisms when the CPU VIC port is not used.

注
Address location 0x00000000 in the VIM RAM is reserved for the phantom interrupt ISR
entry; therefore only request channels 0..94 can be used and are offset by 1 address in the
VIM RAM.
注
The EMIF_nWAIT signal has a pull-up on it. The EMIF module generates a "Wait Rise"
interrupt whenever it detects a rising edge on the EMIF_nWAIT signal. This interrupt
condition is indicated as soon as the device is powered up. This can be ignored if the
EMIF_nWAIT signal is not used in the application. If the EMIF_nWAIT signal is actually used
in the application, then the external slave memory must always drive the EMIF_nWAIT signal
such that an interrupt is not caused due to the default pull-up on this signal.
注
The lower-order interrupt channels are higher priority channels than the higher-order interrupt
channels.
注
The application can change the mapping of interrupt sources to the interrupt channels via the
interrupt channel control registers (CHANCTRLx) inside the VIM module.

6.16.2 Default DMA Request Map
The DMA module on this microcontroller has 16 channels and up to 32 hardware DMA requests. The
module contains DREQASIx registers which are used to map the DMA requests to the DMA channels. By
default, channel 0 is mapped to request 0, channel 1 to request 1, and so on.
Some DMA requests have multiple sources, as shown in 表 6-33. The application must ensure that only
one of these DMA request sources is enabled at any time.

6.17 Real Time Interrupt Module
The real-time interrupt (RTI) module provides timer functionality for operating systems and for
benchmarking code. The RTI module can incorporate several counters that define the timebases needed
for scheduling an operating system.
The timers also allow you to benchmark certain areas of code by reading the values of the counters at the
beginning and the end of the desired code range and calculating the difference between the values.
In addition the RTI provides a mechanism to synchronize the operating system to the FlexRay
communication cycle. Clock supervision can detect issues on the FlexRay bus with an automatic switch to
an internally generated timebase.
6.17.1 Features
The RTI module has the following features:
•
•
Two independent 64 bit counter blocks
Four configurable compares for generating operating system ticks or DMA requests. Each event can
be driven by either counter block 0 or counter block 1.
•
One counter block usable for application synchronization to FlexRay network including clock
supervision
•
•
Fast enabling/disabling of events
Two time-stamp (capture) functions for system or peripheral interrupts, one for each counter block
6.17.2 Block Diagrams
图 6-17 shows a high-level block diagram for one of the two 64-bit counter blocks inside the RTI module.
Both the counter blocks are identical except the Network Time Unit (NTUx) inputs are only available as
time base inputs for the counter block 0.

6.17.3 Clock Source Options
The RTI module uses the RTI1CLK clock domain for generating the RTI time bases.
The application can select the clock source for the RTI1CLK by configuring the RCLKSRC register in the
System module at address 0xFFFFFF50. The default source for RTI1CLK is VCLK.
For more information on clock sources refer to 表 6-8 and 表 6-13.
6.17.4 Network Time Synchronization Inputs
The RTI module supports 4 Network Time Unit (NTU) inputs that signal internal system events, and which
can be used to synchronize the time base used by the RTI module. On this device, these NTU inputs are
connected as shown below.

6.18 Error Signaling Module
The Error Signaling Module (ESM) manages the various error conditions on the TMS570 microcontroller.
The error condition is handled based on a fixed severity level assigned to it. Any severe error condition
can be configured to drive a low level on a dedicated device terminal called nERROR. This can be used
as an indicator to an external monitor circuit to put the system into a safe state.
6.18.1 Features
The features of the Error Signaling Module are:
•
128 interrupt/error channels are supported, divided into 3 different groups
–
–
–
64 channels with maskable interrupt and configurable error pin behavior
32 error channels with non-maskable interrupt and predefined error pin behavior
32 channels with predefined error pin behavior only
•
•
•
Error pin to signal severe device failure
Configurable timebase for error signal
Error forcing capability
6.18.2 ESM Channel Assignments
The Error Signaling Module (ESM) integrates all the device error conditions and groups them in the order
of severity. Group1 is used for errors of the lowest severity while Group3 is used for errors of the highest
severity. The device response to each error is determined by the severity group it is connected to. 表 6-36
shows the channel assignment for each group.

6.20 Digital Windowed Watchdog
This device includes a digital windowed watchdog (DWWD) module that protects against runaway code
execution.
The DWWD module allows the application to configure the time window within which the DWWD module
expects the application to service the watchdog. A watchdog violation occurs if the application services the
watchdog outside of this window, or fails to service the watchdog at all. The application can choose to
generate a system reset or a non-maskable interrupt to the CPU in case of a watchdog violation.
The watchdog is disabled by default and must be enabled by the application. Once enabled, the watchdog
can only be disabled upon a system reset.

6.21.6 Advanced JTAG Security Module
This device includes an Advanced JTAG Security Module (AJSM). which provides maximum security to
the device’s memory content by allowing users to secure the device after programming.

图 6-21. AJSM Unlock
The device is unsecure by default by virtue of a 128-bit visible unlock code programmed in the OTP
address 0xF0000000.The OTP contents are XOR-ed with the "Unlock By Scan" register contents. The
outputs of these XOR gates are again combined with a set of secret internal tie-offs. The output of this
combinational logic is compared against a secret hard-wired 128-bit value. A match results in the
UNLOCK signal being asserted, so that the device is now unsecure.
A user can secure the device by changing at least one bit in the visible unlock code from 1 to 0. Changing
a 0 to 1 is not possible since the visible unlock code is stored in the One Time Programmable (OTP) flash
region. Also, changing all the 128 bits to zeros is not a valid condition and will permanently secure the
device.
Once secured, a user can unsecure the device by scanning an appropriate value into the "Unlock By
Scan" register of the AJSM module. The value to be scanned is such that the XOR of the OTP contents
and the Unlock-By-Scan register contents results in the original visible unlock code.
The Unlock-By-Scan register is reset only upon asserting power-on reset (nPORRST).
A secure device only permits JTAG accesses to the AJSM scan chain via the Secondary Tap 2 of the
ICEPick module. All other secondary taps, test taps and the boundary scan interface are not accessible in
this state.

6.21.7 Embedded Trace Macrocell (ETM-R4)
The device contains a ETM-R4 module with a 32-bit internal data port. The ETM-R4 module is connected
to a TPIU with a 32-bit data bus; the TPIU provides a 35-bit (32-bit data, 3-bit control) external interface
for trace. The ETM-R4 is CoreSight compliant and follows the ETM v3 specification; for more details see
ARM CoreSight ETM-R4 TRM specification.
6.21.7.1 ETM TRACECLKIN Selection
The ETM clock source can be selected as either VCLK or the external ETMTRACECLKIN pin. The
selection is done by the EXTCTRLOUT[1:0] control bits of the TPIU; the default is '00'. The address of this
register is TPIU base address + 0x404.
Before you begin accessing TPIU registers, TPIU should be unlocked via coresight key and 1 or 2 should
be written to this register.

without program intrusion. It can trace all data write or read accesses to internal RAM. In addition, it
provides the capability to directly transfer data to a FIFO to support a CPU-controlled transmission of the
data. The trace data is transmitted over a dedicated external interface.
6.21.8.1 Features
The RTP offers the following features:
•
Two modes of operation - Trace Mode and Direct Data Mode
–
Trace Mode
•
•
•
•
•
•
Non-intrusive data trace on write or read operation
Visibility of RAM content at any time on external capture hardware
Trace of peripheral accesses
Two configurable trace regions for each RAM module to limit amount of data to be traced
FIFO to store data and address of data of multiple read/write operations
Trace of CPU and/or DMA accesses with indication of the master in the transmitted data packet
–
Direct Data Mode
•
Directly write data with the CPU or trace read operations to a FIFO, without transmitting header
and address information
•
•
•
•
Dedicated synchronous interface to transmit data to external devices
Free-running clock generation or clock stop mode between transmissions
Up to 100 Mbit per sec/pin transfer rate for transmitting data
Pins not used in functional mode can be used as GIOs

图 6-29 shows a case with 1 DMM packet per 2 DMMCLK cycles (Mode = Direct Data Mode, data width =
8, portwidth = 4) where none of the packets received by the DMM are sent out, leading to filling up of the
internal buffers. The DMMnENA signal is shown asserted, after the first two packets have been received
and synchronised to the HCLK domain. Here, the DMM has the capacity to accept packets D4x, D5x, D6x,
D7x. Packet D8 would result in an overflow. Once DMMnENA is asserted, the DMM expects to stop
receiving packets after 4 HCLK cycles; once DMMnENA is de-asserted, the DMM can handle packets
immediately (after 0 HCLK cycles).

7.2 Multi-Buffered 12bit Analog-to-Digital Converter
The multibuffered A-to-D converter (MibADC) has a separate power bus for its analog circuitry that
enhances the A-to-D performance by preventing digital switching noise on the logic circuitry which could
be present on VSS and VCC from coupling into the A-to-D analog stage. All A-to-D specifications are given
with respect to ADREFLO unless otherwise noted.

7.2.2 Event Trigger Options
The ADC module supports 3 conversion groups: Event Group, Group1 and Group2. Each of these 3
groups can be configured to be hardware event-triggered. In that case, the application can select from
among 8 event sources to be the trigger for a group's conversions.

For ADEVT, N2HET1 and GIOB trigger sources, the connection to the MibADC1 module
trigger input is made from the output side of the input buffer. This way, a trigger condition
can be generated either by configuring the function as output onto the pad (via the mux
control), or by driving the function from an external trigger source as input. If the mux control
module is used to select different functionality instead of the ADEVT, N2HET1[x] or GIOB[x]
signals, then care must be taken to disable these signals from triggering conversions; there
is no multiplexing on the input connections.
注
For the RTI compare 0 interrupt source, the connection is made directly from the output of
the RTI module. That is, the interrupt condition can be used as a trigger source even if the
actual interrupt is not signaled to the CPU.

(1) The MibADC clock is the ADCLK, generated by dividing down the VCLK by a prescale factor defined by the ADCLOCKCR register bits
4:0.
(2) The sample and hold time for the ADC conversions is defined by the ADCLK frequency and the AD<GP>SAMP register for each
conversion group. The sample time needs to be determined by accounting for the external impedance connected to the input channel as
well as the ADC’s internal impedance.
(3) This is the minimum sample/hold and conversion time that can be achieved. These parameters are dependent on many factors, e.g the
prescale settings.

ZHCSBS0C –OCTOBER 2013–REVISED JANUARY 2015
7.4 Enhanced High-End Timer (N2HET)
The N2HET is an advanced intelligent timer that provides sophisticated timing functions for real-time
applications. The timer is software-controlled, using a reduced instruction set, with a specialized timer
micromachine and an attached I/O port. The N2HET can be used for pulse width modulated outputs,
capture or compare inputs, or general-purpose I/O.. It is especially well suited for applications requiring
multiple sensor information and drive actuators with complex and accurate time pulses.
7.4.1 Features
The N2HET module has the following features:
•
•
•
•
•
Programmable timer for input and output timing functions
Reduced instruction set (30 instructions) for dedicated time and angle functions
160 words of instruction RAM protected by parity
User defined number of 25-bit virtual counters for timer, event counters and angle counters
7-bit hardware counters for some pins allow up to 32-bit resolution in conjunction with the 25-bit virtual
counters
•
•
•
•
Up to 32 pins usable for input signal measurements or output signal generation
Programmable suppression filter for each input pin with adjustable limiting frequency
Low CPU overhead and interrupt load
Efficient data transfer to or from the CPU memory with dedicated High-End-Timer Transfer Unit (HTU)
or DMA
•
Diagnostic capabilities with different loopback mechanisms and pin status readback functionality
7.4.2 N2HET RAM Organization
The timer RAM uses 4 RAM banks, where each bank has two port access capability. This means that one
RAM address may be written while another address is read. The RAM words are 96-bits wide, which are
split into three 32-bit fields (program, control, and data).

7.4.4 N2HET1-N2HET2 Interconnections
In some applications the N2HET resolutions must be synchronized. Some other applications require a
single time base to be used for all PWM outputs and input timing captures.
The N2HET provides such a synchronization mechanism. The Clk_master/slave (HETGCR.16) configures
the N2HET in master or slave mode (default is slave mode). A N2HET in master mode provides a signal
to synchronize the prescalers of the slave N2HET. The slave N2HET synchronizes its loop resolution to
the loop resolution signal sent by the master. The slave does not require this signal after it receives the
first synchronization signal. However, anytime the slave receives the re-synchronization signal from the
master, the slave must synchronize itself again..

7.4.5 N2HET Checking
7.4.5.1 Internal Monitoring
To assure correctness of the high-end timer operation and output signals, the two N2HET modules can be
used to monitor each other’s signals as shown in 图 7-7. The direction of the monitoring is controlled by
the I/O multiplexing control module.

图 7-7. N2HET Monitoring
7.4.5.2 Output Monitoring using Dual Clock Comparator (DCC)
N2HET1[31] is connected as a clock source for counter 1 in DCC1. This allows the application to measure
the frequency of the pulse-width modulated (PWM) signal on N2HET1[31].
Similarly, N2HET2[0] is connected as a clock source for counter 1 in DCC2. This allows the application to
measure the frequency of the pulse-width modulated (PWM) signal on N2HET2[0].
Both N2HET1[31] and N2HET2[0] can be configured to be internal-only channels. That is, the connection
to the DCC module is made directly from the output of the N2HETx module (from the input of the output
buffer).
For more information on DCC see 节 6.7.3.
7.4.6 Disabling N2HET Outputs
Some applications require the N2HET outputs to be disabled under some fault condition. The N2HET
module provides this capability via the "Pin Disable" input signal. This signal, when driven low, causes the
N2HET outputs identified by a programmable register (HETPINDIS) to be tri-stated. Please refer to the
device specific technical reference manual for more details on the "N2HET Pin Disable" feature.
GIOA[5] is connected to the "Pin Disable" input for N2HET1, and GIOB[2] is connected to the "Pin
Disable" input for N2HET2.

7.5 FlexRay Interface
The FlexRay module performs communication according to the FlexRay protocol specification v2.1. The
sample clock bitrate can be programmed to values up to 10 MBit per second. Additional bus driver (BD)
hardware is required for connection to the physical layer.
For communication on a FlexRay network, individual message buffers with up to 254 data bytes are
configurable. The message storage consists of a single-ported message RAM that holds up to 128
message buffers. All functions concerning the handling of messages are implemented in the message
handler. Those functions are the acceptance filtering, the transfer of messages between the two FlexRay
Channel Protocol Controllers and the message RAM, maintaining the transmission schedule as well as
providing message status information.
The register set of the FlexRay module can be accessed directly by the CPU via the VBUS interface.
These registers are used to control, configure and monitor the FlexRay channel protocol controllers,
message handler, global time unit, system universal control, frame/symbol processing, network
management, interrupt control, and to access the message RAM via the input / output buffer.
7.5.1 Features
The FlexRay module has the following features:
•
•
•
•
Conformance with FlexRay protocol specification v2.1
Data rates of up to 10 Mb/s on each channel
Up to 128 message buffers
8 Kbyte of message RAM for storage of, for example, 128 message buffers with max 48 byte data
section or up to 30 message buffers with 254 byte data section
•
•
•
Configuration of message buffers with different payload lengths
One configurable receive FIFO
Each message buffer can be configured as receive buffer, as transmit buffer or as part of the receive
FIFO
•
•
CPU access to message buffers via input and output buffer
FlexRay transfer unit (FTU) for automatic data transfer between data memory and message buffers
without CPU interaction
•
•
•
Filtering for slot counter, cycle counter, and channel ID

7.5.3 FlexRay Transfer Unit
The FlexRay Transfer Unit is able to transfer data between the input buffer (IBF) and output buffer (OBF)
of the communication controller and the system memory without CPU interaction.
Because the FlexRay module is accessed through the FTU, the FTU must be powered up by the setting
bit 23 in the Peripheral Power Down Registers of the System Module before accessing any FlexRay
module register.
For more information on the FTU see the TMS570LS31X/TMS570LS21X Technical Reference Manual
(SPNU499).

Typical applications for the SPI include interfacing to external peripherals, such as I/Os, memories, display
drivers, and analog-to-digital converters.
7.10.1 Features
Both Standard and MibSPI modules have the following features:
•
•
•
•
16-bit shift register
Receive buffer register
5-bit baud clock generator
SPICLK can be internally-generated (master mode) or received from an external clock source (slave
mode)
•
•
Each word transferred can have a unique format
SPI I/Os not used in the communication can be used as digital input/output signals

7.10.2 MibSPI Transmit and Receive RAM Organization
The Multibuffer RAM is comprised of 128 buffers. Each entry in the Multibuffer RAM consists of 4 parts: a
16-bit transmit field, a 16-bit receive field, a 16-bit control field and a 16-bit status field. The Multibuffer
RAM can be partitioned into multiple transfer group with variable number of buffers each.
7.10.3 MibSPI Transmit Trigger Events
Each of the transfer groups can be configured individually. For each of the transfer groups a trigger event
and a trigger source can be chosen. A trigger event can be for example a rising edge or a permanent low
level at a selectable trigger source. For example, up to 15 trigger sources are available which can be
utilized by each transfer group. These trigger options are listed in 表 7-21 for MIBSPI1, 节 7.10.3.2 for
MIBSPI3 and 节 7.10.3.3 for MibSPI5.

For N2HET1 trigger sources, the connection to the MibSPI1 module trigger input is made
from the input side of the output buffer (at the N2HET1 module boundary). This way, a
trigger condition can be generated even if the N2HET1 signal is not selected to be output on
the pad.
注
For GIOx trigger sources, the connection to the MibSPI1 module trigger input is made from
the output side of the input buffer. This way, a trigger condition can be generated either by
selecting the GIOx pin as an output pin plus selecting the pin to be a GIOx pin, or by driving
the GIOx pin from an external trigger source. If the mux control module is used to select
different functionality instead of the GIOx signal, then care must be taken to disable GIOx
from triggering MibSPI1 transfers; there is no multiplexing on the input connections.

(1) The MASTER bit (SPIGCR1.0) is set and the CLOCK PHASE bit (SPIFMTx.16) is set.
(2) tc(VCLK) = interface clock cycle time = 1 / f(VCLK)
(3) For rise and fall timings, see 表 5-6.
(4) When the SPI is in master mode, the following must be true:
For PS values from 1 to 255: tc(SPC)M ≥ (PS +1) tc(VCLK) ≥ 40 ns, where PS is the prescale value set in the SPIFMTx.[15:8] register bits.
For PS values of 0: tc(SPC)M = 2tc(VCLK) ≥ 40 ns.
The external load on the SPICLK pin must be less than 60 pF.
(5) The active edge of the SPICLK signal referenced is controlled by the CLOCK POLARITY bit (SPIFMTx.17).
(6) C2TDELAY and T2CDELAY is programmed in the SPIDELAY register

7.11 Ethernet Media Access Controller
The Ethernet Media Access Controller (EMAC) provides an efficient interface between the CPU and the
network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps
in either half- or full-duplex mode, with hardware flow control and quality of service (QoS) support.
The EMAC controls the flow of packet data from the device to the PHY. The MDIO module controls PHY
configuration and status monitoring.
Both the EMAC and the MDIO modules interface to the device through a custom interface that allows
efficient data transmission and reception. This custom interface is referred to as the EMAC control
module, and is considered integral to the EMAC/MDIO peripheral. The control module is also used to
multiplex and control interrupts.

8 Device and Documentation Support
8.1 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
devices. Each commercial family member has one of three prefixes: TMX, TMP, or TMS (for example,
TMS570LS3137). These prefixes represent evolutionary stages of product development from engineering
prototypes (TMX) through fully qualified production devices/tools (TMS).
Device development evolutionary flow:
TMX
TMP
TMS
Experimental device that is not necessarily representative of the final device's electrical
specifications.
Final silicon die that conforms to the device's electrical specifications but has not completed
quality and reliability verification.
Fully-qualified production device.
TMX and TMP devices are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS devices have been characterized fully, and the quality and reliability of the device have been
demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production
system because their expected end-use failure rate still is undefined. Only qualified production devices are
to be used.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
