Processor Architecture
The SAL-XC866 is based on a high-performance 8-bit Central Processing Unit (CPU)
that is compatible with the standard 8051 processor. While the standard 8051 processor
is designed around a 12-clock machine cycle, the SAL-XC866 CPU uses a 2-clock
machine cycle. This allows fast access to ROM or RAM memories without wait state.
Access to the Flash memory, however, requires an additional wait state (one machine
cycle). The instruction set consists of 45% one-byte, 41% two-byte and 14% three-byte
instructions.
The SAL-XC866 CPU provides a range of debugging features, including basic stop/start,
single-step execution, breakpoint support and read/write access to the data memory,
program memory and SFRs. Figure 5 shows the CPU functional blocks.

Memory Protection Strategy
The SAL-XC866 memory protection strategy includes:
• Read-out protection: The Flash Memory can be enabled for read-out protection and
ROM memory is always protected.
• Program and erase protection: The Flash memory in all devices can be enabled for
program and erase protection.
Flash memory protection is available in two modes:
• Mode 0: Only the P-Flash is protected; the D-Flash is unprotected
• Mode 1: Both the P-Flash and D-Flash are protected
The selection of each protection mode and the restrictions imposed are summarized in
Table 3.

BSL mode 6, which is used for enabling Flash protection, can also be used for disabling
Flash protection. Here, the programmed password must be provided by the user. A
password match triggers an automatic erase of the read-protected Flash contents, see
Table 4, and the programmed password is erased. The Flash protection is then disabled
upon the next reset.
For XC866-2FR and XC866-4FR devices:
The selection of protection type is summarized in Table 4.

Functional Description
3.2.2
Special Function Register
The Special Function Registers (SFRs) occupy direct internal data memory space in the
range 80H to FFH. All registers, except the program counter, reside in the SFR area. The
SFRs include pointers and registers that provide an interface between the CPU and the
on-chip peripherals. As the 128-SFR range is less than the total number of registers
required, address extension mechanisms are required to increase the number of
addressable SFRs. The address extension mechanisms include:
• Mapping
• Paging
3.2.2.1 Address Extension by Mapping
Address extension is performed at the system level by mapping. The SFR area is
extended into two portions: the standard (non-mapped) SFR area and the mapped SFR
area. Each portion supports the same address range 80H to FFH, bringing the number
of addressable SFRs to 256. The extended address range is not directly controlled by
the CPU instruction itself, but is derived from bit RMAP in the system control register
SYSCON0 at address 8FH. To access SFRs in the mapped area, bit RMAP in SFR
SYSCON0 must be set. Alternatively, the SFRs in the standard area can be accessed
by clearing bit RMAP. The SFR area can be selected as shown in Figure 7.

Note: The RMAP bit must be cleared/set by ANL or ORL instructions. The rest bits of
SYSCON0 should not be modified.
As long as bit RMAP is set, the mapped SFR area can be accessed. This bit is not
cleared automatically by hardware. Thus, before standard/mapped registers are
accessed, bit RMAP must be cleared/set, respectively, by software.

3.2.2.2 Address Extension by Paging
Address extension is further performed at the module level by paging. With the address
extension by mapping, the SAL-XC866 has a 256-SFR address range. However, this is
still less than the total number of SFRs needed by the on-chip peripherals. To meet this
requirement, some peripherals have a built-in local address extension mechanism for
increasing the number of addressable SFRs. The extended address range is not directly
controlled by the CPU instruction itself, but is derived from bit field PAGE in the module
page register MOD_PAGE. Hence, the bit field PAGE must be programmed before
accessing the SFR of the target module. Each module may contain a different number
of pages and a different number of SFRs per page, depending on the specific
requirement. Besides setting the correct RMAP bit value to select the SFR area, the user
must also ensure that a valid PAGE is selected to target the desired SFR. A page inside
the extended address range can be selected as shown in Figure 8.

V1.1, 2012-12
SAL-XC866
Functional Description
In order to access a register located in a page different from the actual one, the current
page must be left. This is done by reprogramming the bit field PAGE in the page register.
Only then can the desired access be performed.
If an interrupt routine is initiated between the page register access and the module
register access, and the interrupt needs to access a register located in another page, the
current page setting can be saved, the new one programmed and finally, the old page
setting restored. This is possible with the storage fields MOD_STx (x = 0 - 3) for the save
and restore action of the current page setting. By indicating which storage bit field should
be used in parallel with the new page value, a single write operation can:
• Save the contents of PAGE in MOD_STx before overwriting with the new value
(this is done in the beginning of the interrupt routine to save the current page setting
and program the new page number); or
• Overwrite the contents of PAGE with the contents of MOD_STx, ignoring the value
written to the bit positions of PAGE
(this is done at the end of the interrupt routine to restore the previous page setting
before the interrupt occurred)

Storage Elements for Paging
With this mechanism, a certain number of interrupt routines (or other routines) can
perform page changes without reading and storing the previously used page information.
The use of only write operations makes the system simpler and faster. Consequently,
this mechanism significantly improves the performance of short interrupt routines.
The SAL-XC866 supports local address extension for:
• Parallel Ports
• Analog-to-Digital Converter (ADC)
• Capture/Compare Unit 6 (CCU6)
• System Control Registers

Flash Memory
The Flash memory provides an embedded user-programmable non-volatile memory,
allowing fast and reliable storage of user code and data. It is operated from a single 2.5 V
supply from the Embedded Voltage Regulator (EVR) and does not require additional
programming or erasing voltage. The sectorization of the Flash memory allows each
sector to be erased independently.

In-System Programming (ISP) via UART
In-Application Programming (IAP)
Error Correction Code (ECC) for dynamic correction of single-bit errors
Background program and erase operations for CPU load minimization
Support for aborting erase operation
1)
Minimum program width of 32-byte for D-Flash and 32-byte for P-Flash
1-sector minimum erase width
1-byte read access
Flash is delivered in erased state (read all zeros)
Operating supply voltage: 2.5 V ± 7.5 %
2)
Read access time: 3 × tCCLK = 120 ns
3)
Program time: 209440 / fSYS = 2.8 ms
3)
Erase time: 8175360 / fSYS = 109 ms
1)
P-Flash: 32-byte wordline can only be programmed once, i.e., one gate disturb allowed.
D-Flash: 32-byte wordline can be programmed twice, i.e., two gate disturbs allowed.
2)
3)
fsys = 75 MHz ± 7.5% (fCCLK = 25 MHz ± 7.5 %) is the maximum frequency range for Flash read access.
fsys = 75 MHz ± 7.5% is the only frequency range for Flash programming and erasing. fsysmin is used for
obtaining the worst case timing.

One cycle refers to the programming of all wordlines in a sector and erasing of sector. The Flash endurance
data specified in Table 14 is valid only if the following conditions are fulfilled:
- the maximum number of erase cycles per Flash sector must not exceed 100,000 cycles.
- the maximum number of erase cycles per Flash bank must not exceed 300,000 cycles.
- the maximum number of program cycles per Flash bank must not exceed 2,500,000 cycles.
2)
3)
If no Flash is used for data, the Program Flash size can be up to the maximum Flash size available in the
device variant. Having more Data Flash will mean less Flash is available for Program Flash.
For T =125 to 150°C, refers to programming of second 8 bytes (bytes 8 to 15) per WL

16 Kbytes of embedded Flash memory. These Flash memory sizes are made up of two
or four 4-Kbyte Flash banks, respectively. Each Flash device consists of Program Flash
(P-Flash) bank(s) and a single Data Flash (D-Flash) bank with different sectorization
shown in Figure 10. Both types can be used for code and data storage. The label “Data”
neither implies that the D-Flash is mapped to the data memory region, nor that it can only
be used for data storage. It is used to distinguish the different Flash bank sectorizations.

Flash Bank Sectorization
The internal structure of each Flash bank represents a sector architecture for flexible
erase capability. The minimum erase width is always a complete sector, and sectors can
be erased separately or in parallel. Contrary to standard EPROMs, erased Flash
memory cells contain 0s.
The D-Flash bank is divided into more physical sectors for extended erasing and
reprogramming capability; even numbers for each sector size are provided to allow
greater flexibility and the ability to adapt to a wide range of application requirements.

Flash Programming Width
For the P-Flash banks, a programmed wordline (WL) must be erased before it can be
reprogrammed as the Flash cells can only withstand one gate disturb. This means that
the entire sector containing the WL must be erased since it is impossible to erase a
single WL.
For the D-Flash bank, the same WL can be programmed twice before erasing is required
as the Flash cells are able to withstand two gate disturbs. Hence, it is possible to
program the same WL, for example, with 16 bytes of data in two times (see Figure 11).
32 bytes (1 WL)

Note: A Flash memory cell can be programmed
from 0 to 1, but not from 1 to 0.

D-Flash Programming
Note: When programming a D-Flash WL the second time, the previously programmed
Flash memory cells (whether 0s or 1s) should be reprogrammed with 0s to retain
its original contents and to prevent “over-programming”.

Interrupt System
The XC800 Core supports one non-maskable interrupt (NMI) and 14 maskable interrupt
requests. In addition to the standard interrupt functions supported by the core, e.g.,
configurable interrupt priority and interrupt masking, the XC866 interrupt system
provides extended interrupt support capabilities such as the mapping of each interrupt
vector to several interrupt sources to increase the number of interrupt sources
supported, and additional status registers for detecting and determining the interrupt
source.

Each interrupt source has an associated interrupt vector address. This vector is
accessed to service the corresponding interrupt source request. The interrupt service of
each interrupt source can be individually enabled or disabled via an enable bit. The
assignment of the SAL-XC866 interrupt sources to the interrupt vector addresses and
the corresponding interrupt source enable bits are summarized in Table 15.

Interrupt Priority
Each interrupt source, except for NMI, can be individually programmed to one of the four
possible priority levels. The NMI has the highest priority and supersedes all other
interrupts. Two pairs of interrupt priority registers (IP and IPH, IP1 and IPH1) are
available to program the priority level of each non-NMI interrupt vector.
A low-priority interrupt can be interrupted by a high-priority interrupt, but not by another
interrupt of the same or lower priority. Further, an interrupt of the highest priority cannot
be interrupted by any other interrupt source.
If two or more requests of different priority levels are received simultaneously, the
request of the highest priority is serviced first. If requests of the same priority are
received simultaneously, then an internal polling sequence determines which request is
serviced first. Thus, within each priority level, there is a second priority structure
determined by the polling sequence shown in Table 16.

Parallel Ports
The SAL-XC866 has 27 port pins organized into four parallel ports, Port 0 (P0) to Port 3
(P3). Each pin has a pair of internal pull-up and pull-down devices that can be individually
enabled or disabled. Ports P0, P1 and P3 are bidirectional and can be used as general
purpose input/output (GPIO) or to perform alternate input/output functions for the on-chip
peripherals. When configured as an output, the open drain mode can be selected. Port
P2 is an input-only port, providing general purpose input functions, alternate input
functions for the on-chip peripherals, and also analog inputs for the Analog-to-Digital
Converter (ADC).
Bidirectional Port Features:
• Configurable pin direction
• Configurable pull-up/pull-down devices
• Configurable open drain mode
• Transfer of data through digital inputs and outputs (general purpose I/O)
• Alternate input/output for on-chip peripherals

Power Supply System with Embedded Voltage Regulator
The SAL-XC866 microcontroller requires two different levels of power supply:
• 3.3 V or 5.0 V for the Embedded Voltage Regulator (EVR) and Ports
• 2.5 V for the core, memory, on-chip oscillator, and peripherals
Figure 19 shows the SAL-XC866 power supply system. A power supply of 3.3 V or
5.0 V must be provided from the external power supply pin. The 2.5 V power supply for
the logic is generated by the EVR. The EVR helps to reduce the power consumption of
the whole chip and the complexity of the application board design.
The EVR consists of a main voltage regulator and a low power voltage regulator. In
active mode, both voltage regulators are enabled. In power-down mode, the main
voltage regulator is switched off, while the low power voltage regulator continues to
function and provide power supply to the system with low power consumption.

Reset Control
The SAL-XC866 has five types of reset: power-on reset, hardware reset, watchdog timer
reset, power-down wake-up reset, and brownout reset.
When the SAL-XC866 is first powered up, the status of certain pins (see Table 18) must
be defined to ensure proper start operation of the device. At the end of a reset sequence,
the sampled values are latched to select the desired boot option, which cannot be
modified until the next power-on reset or hardware reset. This guarantees stable
conditions during the normal operation of the device.
In order to power up the system properly, the external reset pin RESET must be asserted
until V
reaches 0.9*V
. The delay of external reset can be realized by an external
DDC
DDC
capacitor at RESET pin. This capacitor value must be selected so that V
reaches
RESET
0.4 V, but not before V
reaches 0.9* V

DDC.
A typical application example is shown in Figure 20. V
capacitor value is 300 nF.
DDP
V
capacitor value is 220 nF. The capacitor connected to RESET pin is 100 nF.
DDC
Typically, the time taken for V
to reach 0.9*V
is less than 50 μs once V

DDC DDP
reaches 2.3V. Hence, based on the condition that 10% to 90% V
(slew rate) is less

The second type of reset in SAL-XC866 is the hardware reset. This reset function can
be used during normal operation or when the chip is in power-down mode. A reset input
pin RESET is provided for the hardware reset. To ensure the recognition of the hardware
reset, pin RESET must be held low for at least 100 ns.
The Watchdog Timer (WDT) module is also capable of resetting the device if it detects
a malfunction in the system.
Another type of reset that needs to be detected is a reset while the device is in
power-down mode (wake-up reset). While the contents of the static RAM are undefined
after a power-on reset, they are well defined after a wake-up reset from power-down
mode.

When the SAL-XC866 is reset, it must identify the type of configuration with which to start
the different modes once the reset sequence is complete. Thus, boot configuration
information that is required for activation of special modes and conditions needs to be
applied by the external world through input pins. After power-on reset or hardware reset,
the pins MBC, TMS and P0.0 collectively select the different boot options. Table 18
shows the available boot options in the SAL-XC866.

Clock Generation Unit
The Clock Generation Unit (CGU) allows great flexibility in the clock generation for the
SAL-XC866. The power consumption is indirectly proportional to the frequency, whereas
the performance of the microcontroller is directly proportional to the frequency. During
user program execution, the frequency can be programmed for an optimal ratio between
performance and power consumption. Therefore the power consumption can be
adapted to the actual application state.
Features:
• Phase-Locked Loop (PLL) for multiplying clock source by different factors
• PLL Base Mode
• Prescaler Mode
• PLL Mode
• Power-down mode support
The CGU consists of an oscillator circuit and a PLL.In the SAL-XC866, the oscillator can
be from either of these two sources: the on-chip oscillator (10 MHz) or the external
oscillator (4 MHz to 12 MHz). The term “oscillator” is used to refer to both on-chip
oscillator and external oscillator, unless otherwise stated. After the reset, the on-chip
oscillator will be used by default.The external oscillator can be selected via software. In
addition, the PLL provides a fail-safe logic to perform oscillator run and loss-of-lock
detection. This allows emergency routines to be executed for system recovery or to
perform system shut down.

Recommended External Oscillator Circuits
The oscillator circuit, a Pierce oscillator, is designed to work with both, an external crystal
oscillator or an external stable clock source. It basically consists of an inverting amplifier
and a feedback element with XTAL1 as input, and XTAL2 as output.
When using a crystal, a proper external oscillator circuitry must be connected to both
pins, XTAL1 and XTAL2. The crystal frequency can be within the range of 4 MHz
to 12 MHz. Additionally, it is necessary to have two load capacitances CX1 and CX2, and
depending on the crystal type, a series resistor RX2, to limit the current. A test resistor
RQ may be temporarily inserted to measure the oscillation allowance (negative
resistance) of the oscillator circuitry. RQ values are typically specified by the crystal
vendor. The CX1 and CX2 values shown in Figure 23 can be used as starting points for
the negative resistance evaluation and for non-productive systems. The exact values
and related operating range are dependent on the crystal frequency and have to be
determined and optimized together with the crystal vendor using the negative resistance
method. Oscillation measurement with the final target system is strongly recommended
to verify the input amplitude at XTAL1 and to determine the actual oscillation allowance
(margin negative resistance) for the oscillator-crystal system.
When using an external clock signal, the signal must be connected to XTAL1. XTAL2 is
left open (unconnected).
The oscillator can also be used in combination with a ceramic resonator. The final
circuitry must also be verified by the resonator vendor.
Figure 23 shows the recommended external oscillator circuitries for both operating
modes, external crystal mode and external input clock mode.

Clock Management
The CGU generates all clock signals required within the microcontroller from a single
clock, f . During normal system operation, the typical frequencies of the different
sys
modules are as follow:
• CPU clock: CCLK, SCLK = 25 MHz
• CCU6 clock: FCLK = 25 MHz
• Other peripherals: PCLK = 25 MHz
• Flash Interface clock: CCLK3 = 75 MHz and CCLK = 25 MHz
In addition, different clock frequency can output to pin CLKOUT(P0.0). The clock output
frequency can further be divided by 2 using toggle latch (bit TLEN is set to 1), the
resulting output frequency has 50% duty cycle. Figure 24 shows the clock distribution of

Watchdog Timer
The Watchdog Timer (WDT) provides a highly reliable and secure way to detect and
recover from software or hardware failures. The WDT is reset at a regular interval that is
predefined by the user. The CPU must service the WDT within this interval to prevent the
WDT from causing an SAL-XC866 system reset. Hence, routine service of the WDT
confirms that the system is functioning properly. This ensures that an accidental
malfunction of the SAL-XC866 will be aborted in a user-specified time period. In debug
mode, the WDT is suspended and stops counting. Therefore, there is no need to refresh
the WDT during debugging.
Features:
• 16-bit Watchdog Timer
• Programmable reload value for upper 8 bits of timer
• Programmable window boundary
• Selectable input frequency of f

16-bit timer is realized as two concatenated 8-bit timers. The upper 8 bits of the WDT

access. Figure 26 shows the block diagram of the WDT unit.

Functional Description
If the WDT is not serviced before the timer overflow, a system malfunction is assumed.
As a result, the WDT NMI is triggered (assert WDTTO) and the reset prewarning is
entered. The prewarning period lasts for 30 count, after which the system is reset
H
(assert WDTRST).
The WDT has a “programmable window boundary” which disallows any refresh during
the WDT’s count-up. A refresh during this window boundary constitutes an invalid
access to the WDT, causing the reset prewarning to be entered but without triggering the
WDT NMI. The system will still be reset after the prewarning period is over. The window
boundary is from 0000 to the value obtained from the concatenation of WDTWINB and
H
00 .

After being serviced, the WDT continues counting up from the value (<WDTREL> * 2 ).
The time period for an overflow of the WDT is programmable in two ways:
• the input frequency to the WDT can be selected to be either f
/2 or f
/128
PCLK
PCLK
• the reload value WDTREL for the high byte of WDT can be programmed in register

If the Window-Boundary Refresh feature of the WDT is enabled, the period P

between servicing the WDT and the next overflow is shortened if WDTWINB is greater
than WDTREL, see Figure 27. This period can be calculated using the same formula by
replacing WDTREL with WDTWINB. For this feature to be useful, WDTWINB should not
be smaller than WDTREL.

Universal Asynchronous Receiver/Transmitter
The Universal Asynchronous Receiver/Transmitter (UART) provides a full-duplex
asynchronous receiver/transmitter, i.e., it can transmit and receive simultaneously. It is
also receive-buffered, i.e., it can commence reception of a second byte before a
previously received byte has been read from the receive register. However, if the first
byte still has not been read by the time reception of the second byte is complete, one of
the bytes will be lost.
Features:
• Full-duplex asynchronous modes
– 8-bit or 9-bit data frames, LSB first
– fixed or variable baud rate
• Receive buffered
• Multiprocessor communication
• Interrupt generation on the completion of a data transmission or reception
The UART can operate in four asynchronous modes as shown in Table 24. Data is
transmitted on TXD and received on RXD.

Baud-rate Generator Circuitry
The baud rate timer is a count-down timer and is clocked by either the output of the
fractional divider (f ) if the fractional divider is enabled (FDCON.FDEN = 1), or the
MOD
output of the prescaler (f ) if the fractional divider is disabled (FDEN = 0). For baud rate
DIV
generation, the fractional divider must be configured to fractional divider mode
(FDCON.FDM = 0). This allows the baud rate control run bit BCON.R to be used to start
or stop the baud rate timer. At each timer underflow, the timer is reloaded with the 8-bit
reload value in register BG and one clock pulse is generated for the serial channel.
Enabling the fractional divider in normal divider mode (FDEN = 1 and FDM = 1) stops the
baud rate timer and nullifies the effect of bit BCON.R. See Section 3.12.
The baud rate (f ) value is dependent on the following parameters:
BR
• Input clock f
• Prescaling factor (2
PCLK
BRPRE
) defined by bit field BRPRE in register BCON
• Fractional divider (STEP/256) defined by register FDSTEP
(to be considered only if fractional divider is enabled and operating in fractional divider
mode)

The maximum baud rate that can be generated is limited to fPCLK/32. Hence, for a module
clock of 25 MHz, the maximum achievable baud rate is 0.78 MBaud.
Standard LIN protocol can support a maximum baud rate of 20kHz, the baud rate
accuracy is not critical and the fractional divider can be disabled. Only the prescaler is
used for auto baud rate calculation. For LIN fast mode, which supports the baud rate of
20kHz to 115.2kHz, the higher baud rates require the use of the fractional divider for
greater accuracy.
Table 25 lists the various commonly used baud rates with their corresponding parameter
settings and deviation errors. The fractional divider is disabled and a module clock of
25 MHz is used.

Baud Rate Generation using Timer 1
In UART modes 1 and 3, Timer 1 can be used for generating the variable baud rates. In
theory, this timer could be used in any of its modes. But in practice, it should be set into
auto-reload mode (Timer 1 mode 2), with its high byte set to the appropriate value for the
required baud rate. The baud rate is determined by the Timer 1 overflow rate and the
value of SMOD as follows:
[3.1]

SMOD × fPCLK
Mode 1, 3 baud rate= ----------------------------------------------------
32 × 2 × (256 – TH1)
3.12
Normal Divider Mode (8-bit Auto-reload Timer)
Setting bit FDM in register FDCON to 1 configures the fractional divider to normal divider
mode, while at the same time disables baud rate generation (see Figure 28). Once the
fractional divider is enabled (FDEN = 1), it functions as an 8-bit auto-reload timer (with
no relation to baud rate generation) and counts up from the reload value with each input
clock pulse. Bit field RESULT in register FDRES represents the timer value, while bit
field STEP in register FDSTEP defines the reload value. At each timer overflow, an
overflow flag (FDCON.NDOV) will be set and an interrupt request generated. This gives
an output clock fMOD that is 1/n of the input clock fDIV, where n is defined by 256 - STEP.
The output frequency in normal divider mode is derived as follows:

LIN Protocol
The UART can be used to support the Local Interconnect Network (LIN) protocol for both
master and slave operations. The LIN baud rate detection feature provides the capability
to detect the baud rate within LIN protocol using Timer 2. This allows the UART to be
synchronized to the LIN baud rate for data transmission and reception.
LIN is a holistic communication concept for local interconnected networks in vehicles.
The communication is based on the SCI (UART) data format, a single-master/multiple-
slave concept, a clock synchronization for nodes without stabilized time base. An
attractive feature of LIN is self-synchronization of the slave nodes without a crystal or
ceramic resonator, which significantly reduces the cost of hardware platform. Hence, the
baud rate must be calculated and returned with every message frame.
The structure of a LIN frame is shown in Figure 29. The frame consists of the:
• header, which comprises a Break (13-bit time low), Synch Byte (55 ), and ID field
H
• response time
• data bytes (according to UART protocol)
• checksum

LIN Header Transmission
LIN header transmission is only applicable in master mode. In the LIN communication,
a master task decides when and which frame is to be transferred on the bus. It also
identifies a slave task to provide the data transported by each frame. The information
needed for the handshaking between the master and slave tasks is provided by the
master task through the header portion of the frame.
The header consists of a break and synch pattern followed by an identifier. Among these
three fields, only the break pattern cannot be transmitted as a normal 8-bit UART data.
Data Sheet
72
V1.1, 2012-12
SAL-XC866
Functional Description
The break must contain a dominant value of 13 bits or more to ensure proper
synchronization of slave nodes.
In the LIN communication, a slave task is required to be synchronized at the beginning
of the protected identifier field of frame. For this purpose, every frame starts with a
sequence consisting of a break field followed by a synch byte field. This sequence is
unique and provides enough information for any slave task to detect the beginning of a
new frame and be synchronized at the start of the identifier field.
Upon entering LIN communication, a connection is established and the transfer speed
(baud rate) of the serial communication partner (host) is automatically synchronized in
the following steps:
STEP 1: Initialize interface for reception and timer for baud rate measurement
STEP 2: Wait for an incoming LIN frame from host
STEP 3: Synchronize the baud rate to the host
STEP 4: Enter for Master Request Frame or for Slave Response Frame
Note: Re-synchronization and setup of baud rate are always done for every Master
Request Header or Slave Response Header LIN frame.

High-Speed Synchronous Serial Interface
The High-Speed Synchronous Serial Interface (SSC) supports full-duplex and
half-duplex synchronous communication. The serial clock signal can be generated by
the SSC internally (master mode), using its own 16-bit baud-rate generator, or can be
received from an external master (slave mode). Data width, shift direction, clock polarity
and phase are programmable. This allows communication with SPI-compatible devices
or devices using other synchronous serial interfaces.

• Master and slave mode operation
– Full-duplex or half-duplex operation
• Transmit and receive buffered
• Flexible data format
– Programmable number of data bits: 2 to 8 bits
– Programmable shift direction: LSB or MSB shift first

Capture/Compare Unit 6
The Capture/Compare Unit 6 (CCU6) provides two independent timers (T12, T13), which
can be used for Pulse Width Modulation (PWM) generation, especially for AC-motor
control. The CCU6 also supports special control modes for block commutation and
multi-phase machines.
The timer T12 can function in capture and/or compare mode for its three channels. The
timer T13 can work in compare mode only.
The multi-channel control unit generates output patterns, which can be modulated by
T12 and/or T13. The modulation sources can be selected and combined for the signal
modulation.
Timer T12 Features:
• Three capture/compare channels, each channel can be used either as a capture or as
a compare channel
• Supports generation of a three-phase PWM (six outputs, individual signals for
highside and lowside switches)

ADC Clocking Scheme
A common module clock f
generates the various clock signals used by the analog
ADC
and digital parts of the ADC module:
• f
• f
is input clock for the analog part.
is internal clock for the analog part (defines the time base for conversion length
ADCA
ADCI
and the sample time). This clock is generated internally in the analog part, based on
the input clock f to generate a correct duty cycle for the analog components.
ADCA
• f
is input clock for the digital part.
ADCD
The internal clock for the analog part f
is limited to a maximum frequency of 10 MHz.
ADCI
Therefore, the ADC clock prescaler must be programmed to a value that ensures f
ADCI
does not exceed 10 MHz. The prescaler ratio is selected by bit field CTC in register
GLOBCTR. A prescaling ratio of 32 can be selected when the maximum performance of
the ADC is not required.

Functional Description

On-Chip Debug Support
The On-Chip Debug Support (OCDS) provides the basic functionality required for the
software development and debugging of XC800-based systems.
The OCDS design is based on these principles:
• use the built-in debug functionality of the XC800 Core
• add a minimum of hardware overhead
• provide support for most of the operations by a Monitor Program
• use standard interfaces to communicate with the Host (a Debugger)
Features:
• Set breakpoints on instruction address and within a specified address range
• Set breakpoints on internal RAM address
• Support unlimited software breakpoints in Flash/RAM code region
• Process external breaks
• Step through the program code
The OCDS functional blocks are shown in Figure 34. The Monitor Mode Control (MMC)
block at the center of OCDS system brings together control signals and supports the
overall functionality. The MMC communicates with the XC800 Core, primarily via the
Debug Interface, and also receives reset and clock signals. After processing memory
address and control signals from the core, the MMC provides proper access to the
dedicated extra-memories: a Monitor ROM (holding the code) and a Monitor RAM (for
1)
work-data and Monitor-stack). The OCDS system is accessed through the JTAG ,
which is an interface dedicated exclusively for testing and debugging activities and is not
normally used in an application. The dedicated MBC pin is used for external
configuration and debugging control.
Note: All the debug functionality described here can normally be used only after SAL-
XC866 has been started in OCDS mode.
1)
The pins of the JTAG port can be assigned to either Port 0 (primary) or Ports 1 and 2 (secondary).
User must set the JTAG pins (TCK and TDI) as input during connection with the OCDS system.

An overload current (IOV) through a pin injects a certain error current (IINJ) into the adjacent pins. This error
current adds to the respective pin’s leakage current (IOZ). The amount of error current depends on the
overload current and is defined by the overload coupling factor KOV. The polarity of the injected error current
is inverse compared to the polarity of the overload current that produces it. The total current through a pin is
|ITOT| = |IOZ1| + (|IOV| × KOV). The additional error current may distort the input voltage on analog inputs.

This represents an equivalent switched capacitance. This capacitance is not switched to the reference voltage
at once. Instead of this, smaller capacitances are successively switched to the reference voltage.
The sampling capacity of the conversion C-Network is pre-charged to V
/2 before connecting the input to
AREF
the C-Network. Because of the parasitic elements, the voltage measured at ANx is lower than V
/2.
