XMEGA D3

3. Overview

The XMEGA D3 is a family of low power, high performance and peripheral rich CMOS 8/16-bit

microcontrollers based on the AVR^®enhanced RISC architecture. By execug powerful instruc-

tions in a single clock cycle, the XMEGA D3 achieves throughputs approaching 1 Million

Instructions Per Second (MIPS) per MHz allowing the system designer to optimize power con-

sumption versus processing speed.

The AVR CPU combines a rich instruction set with 32 general purpose working registers. All the

32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent

registers to be accessed in one single instruction, executed in one clock cycle. The resulting

architecture is more code efficient while achieving throughputs many times faster than conven-

tional single-accumulator or CISC based microcontrollers.

The XMEGA D3 devices provide the following features: In-System Programmable Flash with

Read-While-Write capabilities, Internal EEPROM and SRAM, four-channel Event System, Pro-

grammable Multi-level Interrupt Controller, 50 general purpose I/O lines, 16-bit Real Time

Counter (RTC), five flexible 16-bit Timer/Counters with compare modes and PWM, three

USARTs, two Two-Wire Interface (TWIs), two Serial Peripheral Interfaces (SPIs), one 16-chan-

nel 12-bit ADC with optional differential input with programmable gain, two analog comparators

with window mode, programmable Watchdog Timer with separate Internal Oscillator, accurate

internal oscillators with PLL and prescaler and programmable Brown-Out Detection.

The Program and Debug Interface (PDI), a fast 2-pin interface for programming and debugging,

is available.

The XMEGA D3 devices have five software selectable power saving modes. The Idle mode

stops the CPU while allowing the SRAM, Event System, Interrupt Controller and all peripherals

to continue functioning. The Power-down mode saves the SRAM and register contents but stops

the oscillators, disabling all other functions until the next TWI or pin-change interrupt, or Reset.

In Power-save mode, the asynchronous Real Time Counter continues to run, allowing the appli-

cation to maintain a timer base while the rest of the device is sleeping. In Standby mode, the

Crystal/Resonator Oscillator is kept running while the rest of the device is sleeping. This allows

very fast start-up from external crystal combined with low power consumption. In Extended

Standby mode, both the main Oscillator and the Asynchronous Timer continue to run. To further

reduce power consumption, the peripheral clock for each individual peripheral can optionally be

stopped in Active mode and Idle sleep mode.

The device is manufactured using Atmel's high-density nonvolatile memory technology. The pro-

gram Flash memory can be reprogrammed in-system through the PDI. A Bootloader running in

the device can use any interface to download the application program to the Flash memory. The

Bootloader software in the Boot Flash section will continue to run while the Application Flash

section is updated, providing true Read-While-Write operation. By combining an 8/16-bit RISC

CPU with In-System Self-Programmable Flash, the Atmel XMEGA D3 is a powerful microcon-

troller family that provides a highly flexible and cost effective solution for many embedded

applications.

The XMEGA D3 devices are supported with a full suite of program and system development

tools including: C compilers, macro assemblers, program debugger/simulators, programmers,

and evaluation kits.

Overview

The XMEGA D3 uses the 8/16-bit AVR CPU. The main function of the AVR CPU is to ensure

correct program execution. The CPU must therefore be able to access memories, perform calcu-

lations and control peripherals. Interrupt handling is described in a separate section. Figure 6-1

on page 7 shows the CPU block diagram.

The AVR uses a Harvard architecture - with separate memories and buses for program and

data. Instructions in the program memory are executed with a single level pipeline. While one

instruction is being executed, the next instruction is pre-fetched from the program memory.

7

8134D–AVR–12/09

XMEGA D3

This concept enables instructions to be executed in every clock cycle. The program memory is

In-System Re-programmable Flash memory.

6.3

6.4

Register File

The fast-access Register File contains 32 x 8-bit general purpose working registers with a single

clock cycle access time. This allows single-cycle Arithmetic Logic Unit (ALU) operation. In a typ-

ical ALU operation, two operands are output from the Register File, the operation is executed,

and the result is stored back in the Register File - in one clock cycle.

Six of the 32 registers can be used as three 16-bit indirect address register pointers for Data

Space addressing - enabling efficient address calculations. One of these address pointers can

also be used as an address pointer for look up tables in Flash program memory.

ALU - Arithmetic Logic Unit

The high performance Arithmetic Logic Unit (ALU) supports arithmetic and logic operations

between registers or between a constant and a register. Single register operations can also be

executed. Within a single clock cycle, arithmetic operations between general purpose registers

or between a register and an immediate are executed. After an arithmetic or logic operation, the

Status Register is updated to reflect information about the result of the operation.

The ALU operations are divided into three main categories – arithmetic, logical, and bit-func-

tions. Both 8- and 16-bit arithmetic is supported, and the instruction set allows for easy

implementation of 32-bit arithmetic. The ALU also provides a powerful multiplier supporting both

signed and unsigned multiplication and fractional format.

6.5

Program Flow

When the device is powered on, the CPU starts to execute instructions from the lowest address

in the Flash Program Memory ‘0’. The Program Counter (PC) addresses the next instruction to

be fetched. After a reset, the PC is set to location ‘0’.

Program flow is provided by conditional and unconditional jump and call instructions, capable of

addressing the whole address space directly. Most AVR instructions use a 16-bit word format,

while a limited number uses a 32-bit format.

During interrupts and subroutine calls, the return address PC is stored on the Stack. The Stack

is effectively allocated in the general data SRAM, and consequently the Stack size is only limited

by the total SRAM size and the usage of the SRAM. After reset the Stack Pointer (SP) points to

the highest address in the internal SRAM. The SP is read/write accessible in the I/O memory

space, enabling easy implementation of multiple stacks or stack areas. The data SRAM can

easily be accessed through the five different addressing modes supported in the AVR CPU.

Overview

The AVR architecture has two main memory spaces, the Program Memory and the Data Mem-

ory. In addition, the XMEGA D3 features an EEPROM Memory for non-volatile data storage. All

three memory spaces are linear and require no paging. The available memory size configura-

tions are shown in ”Ordering Information” on page 2. In addition each device has a Flash

memory signature row for calibration data, device identification, serial number etc.

Non-volatile memory spaces can be locked for further write or read/write operations. This pre-

vents unrestricted access to the application software.

7.3

In-System Programmable Flash Program Memory

The XMEGA D3 devices contains On-chip In-System Programmable Flash memory for program

storage, see Figure 7-1 on page 10. Since all AVR instructions are 16- or 32-bits wide, each

Flash address location is 16 bits.

The Program Flash memory space is divided into Application and Boot sections. Both sections

have dedicated Lock Bits for setting restrictions on write or read/write operations. The Store Pro-

9

8134D–AVR–12/09

XMEGA D3

gram Memory (SPM) instruction must reside in the Boot Section when used to write to the Flash

memory.

A third section inside the Application section is referred to as the Application Table section which

has separate Lock bits for storage of write or read/write protection. The Application Table sec-

tion can be used for storing non-volatile data or application software.

I/O Memory

All peripherals and modules are addressable through I/O memory locations in the data memory

space. All I/O memory locations can be accessed by the Load (LD/LDS/LDD) and Store

(ST/STS/STD) instructions, transferring data between the 32 general purpose registers in the

CPU and the I/O Memory.

The IN and OUT instructions can address I/O memory locations in the range 0x00 - 0x3F

directly.

I/O registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and

CBI instructions. The value of single bits can be checked by using the SBIS and SBIC instruc-

tions on these registers.

The I/O memory address for all peripherals and modules in XMEGA D3 is shown in the ”Periph-

eral Module Address Map” on page 51.

7.4.2

7.4.3

SRAM Data Memory

The XMEGA D3 devices have internal SRAM memory for data storage.

EEPROM Data Memory

The XMEGA D3 devices have internal EEPROM memory for non-volatile data storage. It is

addressable either in a separate data space or it can be memory mapped into the normal data

memory space. The EEPROM memory supports both byte and page access.

8134D–AVR–12/09

XMEGA D3

7.5

Production Signature Row

The Production Signature Row is a separate memory section for factory programmed data. It

contains calibration data for functions such as oscillators and analog modules.

The production signature row also contains a device ID that identify each microcontroller device

type, and a serial number that is unique for each manufactured device. The device ID for the

available XMEGA D3 devices is shown in Table 7-1 on page 13. The serial number consist of

the production LOT number, wafer number, and wafer coordinates for the device.

The production signature row can not be written or erased, but it can be read from both applica-

tion software and external programming.

User Signature Row

The User Signature Row is a separate memory section that is fully accessible (read and write)

from application software and external programming. The user signature row is one flash page

in size, and is meant for static user parameter storage, such as calibration data, custom serial

numbers or identification numbers, random number seeds etc. This section is not erased by

Chip Erase commands that erase the Flash, and requires a dedicated erase command. This

ensures parameter storage during multiple program/erase session and on-chip debug sessions.

Flash and EEPROM Page Size

The Flash Program Memory and EEPROM data memory is organized in pages. The pages are

word accessible for the Flash and byte accessible for the EEPROM.

Table 7-2 on page 14 shows the Flash Program Memory organization. Flash write and erase

operations are performed on one page at the time, while reading the Flash is done one byte at

the time. For Flash access the Z-pointer (Z[m:n]) is used for addressing. The most significant

bits in the address (FPAGE) gives the page number and the least significant address bits

(FWORD) gives the word in the page.

8.2

Overview

The Event System is a set of features for inter-peripheral communication. It enables the possibil-

ity for a change of state in one peripheral to automatically trigger actions in one or more

peripherals. What changes in a peripheral that will trigger actions in other peripherals are config-

urable by software. It is a simple, but powerful system as it allows for autonomous control of

peripherals without any use of interrupts or CPU resources.

The indication of a change in a peripheral is referred to as an event, and is usually the same as

the interrupt conditions for that peripheral. Events are passed between peripherals using a dedi-

cated routing network called the Event Routing Network. Figure 8-1 on page 16 shows a basic

block diagram of the Event System with the Event Routing Network and the peripherals to which

it is connected. This highly flexible system can be used for simple routing of signals, pin func-

tions or for sequencing of events.

The maximum latency is two CPU clock cycles from when an event is generated in one periph-

eral, until the actions are triggered in one or more other peripherals.

The Event System is functional in both Active and Idle modes.

The Event Routing Network can directly connect together ADCs, Analog Comparators (AC),

I/O ports (PORTx), the Real-time Counter (RTC), Timer/Counters (T/C) and the IR Communica-

tion Module (IRCOM). Events can also be generated from software (CPU).

All events from all peripherals are always routed into the Event Routing Network. This consist of

four multiplexers where each can be configured in software to select which event to be routed

into that event channel. All four event channels are connected to the peripherals that can use

events, and each of these peripherals can be configured to use events from one or more event

channels to automatically trigger a software selectable action.

9.2

Overview

XMEGA D3 has an advanced clock system, supporting a large number of clock sources. It incor-

porates both integrated oscillators, external crystal oscillators and resonators. A high frequency

Phase Locked Loop (PLL) and clock prescalers can be controlled from software to generate a

wide range of clock frequencies from the clock source input.

It is possible to switch between clock sources from software during run-time. After reset the

device will always start up running from the 2 Mhz internal oscillator.

A calibration feature is available, and can be used for automatic run-time calibration of the inter-

nal 2 MHz and 32 MHz oscillators. This reduce frequency drift over voltage and temperature.

A Crystal Oscillator Failure Monitor can be enabled to issue a Non-Maskable Interrupt and

switch to internal oscillator if the external oscillator fails. Figure 9-1 on page 18 shows the princi-

pal clock system in XMEGA D3.

Clock Options

9.3.1

32 kHz Ultra Low Power Internal Oscillator

The 32 kHz Ultra Low Power (ULP) Internal Oscillator is a very low power consumption clock

source. It is used for the Watchdog Timer, Brown-Out Detection and as an asynchronous clock

source for the Real Time Counter. This oscillator cannot be used as the system clock source,

and it cannot be directly controlled from software.

9.3.2

32.768 kHz Calibrated Internal Oscillator

The 32.768 kHz Calibrated Internal Oscillator is a high accuracy clock source that can be used

as the system clock source or as an asynchronous clock source for the Real Time Counter. It is

calibrated during production to provide a default frequency which is close to its nominal

frequency.

9.3.3

9.3.4

9.3.5

32.768 kHz Crystal Oscillator

The 32.768 kHz Crystal Oscillator is a low power driver for an external watch crystal. It can be

used as system clock source or as asynchronous clock source for the Real Time Counter.

0.4 - 16 MHz Crystal Oscillator

The 0.4 - 16 MHz Crystal Oscillator is a driver intended for driving both external resonators and

crystals ranging from 400 kHz to 16 MHz.

2 MHz Run-time Calibrated Internal Oscillator

The 2 MHz Run-time Calibrated Internal Oscillator is a high frequency oscillator. It is calibrated

during production to provide a default frequency which is close to its nominal frequency. The

oscillator can use the 32.768 kHz Calibrated Internal Oscillator or the 32 kHz Crystal Oscillator

as a source for calibrating the frequency run-time to compensate for temperature and voltage

drift hereby optimizing the accuracy of the oscillator.

9.3.6

32 MHz Run-time Calibrated Internal Oscillator

The 32 MHz Run-time Calibrated Internal Oscillator is a high frequency oscillator. It is calibrated

during production to provide a default frequency which is close to its nominal frequency. The

oscillator can use the 32.768 kHz Calibrated Internal Oscillator or the 32 kHz Crystal Oscillator

as a source for calibrating the frequency run-time to compensate for temperature and voltage

drift hereby optimizing the accuracy of the oscillator.

9.3.7

9.3.8

External Clock input

The external clock input gives the possibility to connect a clock from an external source.

PLL with Multiplication factor 2 - 31x

The PLL provides the possibility of multiplying a frequency by any number from 2 to 31. In com-

bination with the prescalers, this gives a wide range of output frequencies from all clock sources.

10. Power Management and Sleep Modes

10.1 Features

• 5 sleep modes

– Idle

– Power-down

– Power-save

– Standby

– Extended standby

• Power Reduction registers to disable clocks to unused peripherals

10.2 Overview

The XMEGA D3 provides various sleep modes tailored to reduce power consumption to a mini-

mum. All sleep modes are available and can be entered from Active mode. In Active mode the

CPU is executing application code. The application code decides when and what sleep mode to

enter. Interrupts from enabled peripherals and all enabled reset sources can restore the micro-

controller from sleep to Active mode.

In addition, Power Reduction registers provide a method to stop the clock to individual peripher-

als from software. When this is done, the current state of the peripheral is frozen and there is no

power consumption from that peripheral. This reduces the power consumption in Active mode

and Idle sleep mode.

10.3 Sleep Modes

10.3.1

Idle Mode

In Idle mode the CPU and Non-Volatile Memory are stopped, but all peripherals including the

Interrupt Controller and Event System are kept running. Interrupt requests from all enabled inter-

rupts will wake the device.

10.3.2

Power-down Mode

In Power-down mode all system clock sources, and the asynchronous Real Time Counter (RTC)

clock source, are stopped. This allows operation of asynchronous modules only. The only inter-

rupts that can wake up the MCU are the Two Wire Interface address match interrupts, and

asynchronous port interrupts, e.g pin change.

10.3.3

10.3.4

Power-save Mode

Power-save mode is identical to Power-down, with one exception: If the RTC is enabled, it will

keep running during sleep and the device can also wake up from RTC interrupts.

Standby Mode

Standby mode is identical to Power-down with the exception that all enabled system clock

sources are kept running, while the CPU, Peripheral and RTC clocks are stopped. This reduces

the wake-up time when external crystals or resonators are used.

20

8134D–AVR–12/09

XMEGA D3

10.3.5

Extended Standby Mode

Extended Standby mode is identical to Power-save mode with the exception that all enabled

system clock sources are kept running while the CPU and Peripheral clocks are stopped. This

reduces the wake-up time when external crystals or resonators are used.

11. System Control and Reset

11.1 Features

• Multiple reset sources for safe operation and device reset

– Power-On Reset

– External Reset

– Watchdog Reset

The Watchdog Timer runs from separate, dedicated oscillator

– Brown-Out Reset

Accurate, programmable Brown-Out levels

– PDI reset

– Software reset

• Asynchronous reset

– No running clock in the device is required for reset

• Reset status register

11.2 Resetting the AVR

During reset, all I/O registers are set to their initial values. The SRAM content is not reset. Appli-

cation execution starts from the Reset Vector. The instruction placed at the Reset Vector should

be an Absolute Jump (JMP) instruction to the reset handling routine. By default the Reset Vector

address is the lowest Flash program memory address, ‘0’, but it is possible to move the Reset

Vector to the first address in the Boot Section.

The I/O ports of the AVR are immediately tri-stated when a reset source goes active.

The reset functionality is asynchronous, so no running clock is required to reset the device.

After the device is reset, the reset source can be determined by the application by reading the

Reset Status Register.

11.3 Reset Sources

11.3.1

11.3.2

11.3.3

Power-On Reset

The MCU is reset when the supply voltage VCC is below the Power-on Reset threshold voltage.

External Reset

The MCU is reset when a low level is present on the RESET pin.

Watchdog Reset

The MCU is reset when the Watchdog Timer period expires and the Watchdog Reset is enabled.

The Watchdog Timer runs from a dedicated oscillator independent of the System Clock. For

more details see ”WDT - Watchdog Timer” on page 23.

11.3.4

11.3.5

Brown-Out Reset

The MCU is reset when the supply voltage VCC is below the Brown-Out Reset threshold voltage

and the Brown-out Detector is enabled. The Brown-out threshold voltage is programmable.

PDI reset

The MCU can be reset through the Program and Debug Interface (PDI).

22

8134D–AVR–12/09

XMEGA D3

11.3.6

Software reset

The MCU can be reset by the CPU writing to a special I/O register through a timed sequence.

12. WDT - Watchdog Timer

12.1 Features

• 11 selectable timeout periods, from 8 ms to 8s.

• Two operation modes

– Standard mode

– Window mode

• Runs from the 1 kHz output of the 32 kHz Ultra Low Power oscillator

• Configuration lock to prevent unwanted changes

12.2 Overview

The XMEGA D3 has a Watchdog Timer (WDT). The WDT will run continuously when turned on

and if the Watchdog Timer is not reset within a software configurable time-out period, the micro-

controller will be reset. The Watchdog Reset (WDR) instruction must be run by software to reset

the WDT, and prevent microcontroller reset.

The WDT has a Window mode. In this mode the WDR instruction must be run within a specified

period called a window. Application software can set the minimum and maximum limits for this

window. If the WDR instruction is not executed inside the window limits, the microcontroller will

be reset.

A protection mechanism using a timed write sequence is implemented in order to prevent

unwanted enabling, disabling or change of WDT settings.

For maximum safety, the WDT also has an Always-on mode. This mode is enabled by program-

ming a fuse. In Always-on mode, application software can not disable the WDT.

13. PMIC - Programmable Multi-level Interrupt Controller

13.1 Features

• Separate interrupt vector for each interrupt

• Short, predictable interrupt response time

• Programmable Multi-level Interrupt Controller

– 3 programmable interrupt levels

– Selectable priority scheme within low level interrupts (round-robin or fixed)

– Non-Maskable Interrupts (NMI)

• Interrupt vectors can be moved to the start of the Boot Section

13.2 Overview

XMEGA D3 has a Programmable Multi-level Interrupt Controller (PMIC). All peripherals can

define three different priority levels for interrupts; high, medium or low. Medium level interrupts

may interrupt low level interrupt service routines. High level interrupts may interrupt both low-

and medium level interrupt service routines. Low level interrupts have an optional round robin

scheme to make sure all interrupts are serviced within a certain amount of time.

The built in oscillator failure detection mechanism can issue a Non-Maskable Interrupt (NMI).

13.3 Interrupt vectors

When an interrupt is serviced, the program counter will jump to the interrupt vector address. The

interrupt vector is the sum of the peripheral’s base interrupt address and the offset address for

specific interrupts in each peripheral. The base addresses for the XMEGA D3 devices are

shown in Table 13-1. Offset addresses for each interrupt available in the peripheral are

described for each peripheral in the XMEGA A manual. For peripherals or modules that have

only one interrupt, the interrupt vector is shown in Table 13-1. The program address is the word

address.

• Flexible pin configuration through dedicated Pin Configuration Register

• Synchronous and/or asynchronous input sensing with port interrupts and events

– Sense both edges

– Sense rising edges

– Sense falling edges

– Sense low level

• Asynchronous wake-up from all input sensing configurations

• Two port interrupts with flexible pin masking

• Highly configurable output driver and pull settings:

–

Totem-pole

• Optional Slew rate control

• Configuration of multiple pins in a single operation

• Read-Modify-Write (RMW) support

• Toggle/clear/set registers for Output and Direction registers

• Clock output on port pin

• Event Channel 7 output on port pin

• Mapping of port registers (virtual ports) into bit accessible I/O memory space

14.2 Overview

The XMEGA D3 devices have flexible General Purpose I/O Ports. A port consists of up to 8 pins,

ranging from pin 0 to pin 7. The ports implement several functions, including synchronous/asyn-

chronous input sensing, pin change interrupts and configurable output settings. All functions are

individual per pin, but several pins may be configured in a single operation.

14.3 I/O configuration

All port pins (Pn) have programmable output configuration. In addition, all port pins have an

inverted I/O function. For an input, this means inverting the signal between the port pin and the

pin register. For an output, this means inverting the output signal between the port register and

the port pin. The inverted I/O function can be used also when the pin is used for alternate

functions.

14.4 Input sensing

• Sense both edges

• Sense rising edges

• Sense falling edges

Input sensing is synchronous or asynchronous depending on the enabled clock for the ports,

and the configuration is shown in Figure 14-7 on page 29.

When a pin is configured with inverted I/O, the pin value is inverted before the input sensing.

14.5 Port Interrupt

Each port has two interrupts with separate priority and interrupt vector. All pins on the port can

be individually selected as source for each of the interrupts. The interrupts are then triggered

according to the input sense configuration for each pin configured as source for the interrupt.

14.6 Alternate Port Functions

In addition to the input/output functions on all port pins, most pins have alternate functions. This

means that other modules or peripherals connected to the port can use the port pins for their

functions, such as communication or pulse-width modulation. ”Pinout and Pin Functions” on

page 46 shows which modules on peripherals that enable alternate functions on a pin, and

which alternate functions that is available on a pin.

• Hi-Resolution Extension (Hi-Res)

• Advanced Waveform Extension (AWEX)

15.2 Overview

XMEGA D3 has five Timer/Counters, four Timer/Counter 0 and one Timer/Counter 1. The differ-

ence between them is that Timer/Counter 0 has four Compare/Capture channels, while

Timer/Counter 1 has two Compare/Capture channels.

The Timer/Counters (T/C) are 16-bit and can count any clock, event or external input in the

microcontroller. A programmable prescaler is available to get a useful T/C resolution. Updates of

Timer and Compare registers are double buffered to ensure glitch free operation. Single slope

PWM, dual slope PWM and frequency generation waveforms can be generated using the Com-

pare Channels.

Through the Event System, any input pin or event in the microcontroller can be used to trigger

input capture, hence no dedicated pins are required for this. The input capture has a noise can-

celler to avoid incorrect capture of the T/C, and can be used to do frequency and pulse width

measurements.

A wide range of interrupt or event sources are available, including T/C Overflow, Compare

match and Capture for each Compare/Capture channel in the T/C.

PORTC has one Timer/Counter 0 and one Timer/Counter1. PORTD, PORTE and PORTF each

have one Timer/Counter 0. Notation of these are TCC0 (Time/Counter C0), TCC1, TCD0, TCE0,

and TCF0, respectively.

16. AWEX - Advanced Waveform Extension

16.1 Features

• Output with complementary output from each Capture channel

• Four Dead Time Insertion (DTI) Units, one for each Capture channel

• 8-bit DTI Resolution

• Separate High and Low Side Dead-Time Setting

• Double Buffered Dead-Time

• Event Controlled Fault Protection

• Single Channel Multiple Output Operation (for BLDC motor control)

• Double Buffered Pattern Generation

16.2 Overview

The Advanced Waveform Extension (AWEX) provides extra features to the Timer/Counter in

Waveform Generation (WG) modes. The AWEX enables easy and safe implementation of for

example, advanced motor control (AC, BLDC, SR, and Stepper) and power control applications.

Any WG output from a Timer/Counter 0 is split into a complimentary pair of outputs when any

AWEX feature is enabled. These output pairs go through a Dead-Time Insertion (DTI) unit that

enables generation of the non-inverted Low Side (LS) and inverted High Side (HS) of the WG

output with dead time insertion between LS and HS switching. The DTI output will override the

normal port value according to the port override setting. Optionally the final output can be

inverted by using the invert I/O setting for the port pin.

The Pattern Generation unit can be used to generate a synchronized bit pattern on the port it is

connected to. In addition, the waveform generator output from Compare Channel A can be dis-

tributed to, and override all port pins. When the Pattern Generator unit is enabled, the DTI unit is

bypassed.

The Fault Protection unit is connected to the Event System. This enables any event to trigger a

fault condition that will disable the AWEX output. Several event channels can be used to trigger

fault on several different conditions.

The AWEX is available for TCC0. The notation of this is AWEXC.

17. Hi-Res - High Resolution Extension

17.1 Features

• Increases Waveform Generator resolution by 2-bits (4x)

• Supports Frequency, single- and dual-slope PWM operation

• Supports the AWEX when this is enabled and used for the same Timer/Counter

17.2 Overview

The Hi-Resolution (Hi-Res) Extension is able to increase the resolution of the waveform genera-

tion output by a factor of 4. When enabled for a Timer/Counter, the Fast Peripheral clock running

at four times the CPU clock speed will be as input to the Timer/Counter.

The High Resolution Extension can also be used when an AWEX is enabled and used with a

Timer/Counter.

XMEGA D3 devices have one Hi-Res Extension that can be enabled for each Timer/Counters

on PORTC. The notation of this is HIRESC.

18.2 Overview

The XMEGA D3 includes a 16-bit Real-time Counter (RTC). The RTC can be clocked from an

accurate 32.768 kHz Crystal Oscillator, the 32.768 kHz Calibrated Internal Oscillator, or from the

32 kHz Ultra Low Power Internal Oscillator. The RTC includes both a Period and a Compare

register. For details, see Figure 18-1.

A wide range of Resolution and Time-out periods can be configured using the RTC. With a max-

imum resolution of 30.5 µs, time-out periods range up to 2000 seconds. With a resolution of 1

second, the maximum time-out period is over 18 hours (65536 seconds).

The Two-Wire Interface (TWI) is a bi-directional wired-AND bus with only two lines, the clock

(SCL) line and the data (SDA) line. The protocol makes it possible to interconnect up to 128 indi-

vidually addressable devices. Since it is a multi-master bus, one or more devices capable of

taking control of the bus can be connected.

The only external hardware needed to implement the bus is a single pull-up resistor for each of

the TWI bus lines. Mechanisms for resolving bus contention are inherent in the TWI protocol.

PORTC and PORTE each has one TWI. Notation of these peripherals are TWIC and TWIE,

respectively.

The Universal Synchronous and Asynchronous serial Receiver and Transmitter (USART) is a

highly flexible serial communication module. The USART supports full duplex communication,

and both asynchronous and clocked synchronous operation. The USART can also be set in

Master SPI mode to be used for SPI communication.

Communication is frame based, and the frame format can be customized to support a wide

range of standards. The USART is buffered in both direction, enabling continued data transmis-

sion without any delay between frames. There are separate interrupt vectors for receive and

transmit complete, enabling fully interrupt driven communication. Frame error and buffer over-

flow are detected in hardware and indicated with separate status flags. Even or odd parity

generation and parity check can also be enabled.

One USART can use the IRCOM module to support IrDA 1.4 physical compliant pulse modula-

tion and demodulation for baud rates up to 115.2 kbps.

PORTC, PORTD, and PORTE each has one USART. Notation of these peripherals are

• 8x4 differential inputs

• 3 internal inputs:

–

Integrated Temperature Sensor

VCC voltage divided by 10

Bandgap voltage

• Software selectable gain of 2, 4, 8, 16, 32 or 64

• Software selectable resolution of 8- or 12-bit.

• Internal or External Reference selection

• Event triggered conversion for accurate timing

• Interrupt/Event on compare result

23.2 Overview

XMEGA D3 devices have one Analog to Digital Converters (ADC), see Figure 23-1 on page 40.

The ADC converts analog voltages to digital values. The ADC has 12-bit resolution and is capa-

ble of converting up to 200 thousand samples per second. The input selection is flexible, and

both single-ended and differential measurements can be performed. The ADC can provide both

signed and unsigned results, and an optional gain stage is available to increase the dynamic

range of the ADC.

It is a Successive Approximation Result (SAR) ADC. A SAR ADC measures one bit of the con-

version result at a time.

ADC measurements can be started by application software or an incoming event from another

peripheral in the device.

Both internal and external analog reference voltages can be used. An accurate internal 1.0V

reference is available.

An integrated temperature sensor is available and the output from this can be measured with the

ADC. The output from the VCC/10 and the Bandgap voltage can also be measured by the ADC.

Each ADC has four MUX selection registers with a corresponding result register. This means

that four channels can be sampled within 1.5 µs without any intervention by the application other

than starting the conversion. The results will be available in the result registers.

The ADC may be configured for 8- or 12-bit result, reducing the minimum conversion time (prop-

agation delay) from 3.5 µs for 12-bit to 2.5 µs for 8-bit result.

ADC conversion results are provided left- or right adjusted with optional ‘1’ or ‘0’ padding. This

eases calculation when the result is represented as a signed integer (signed 16-bit number).

PORTA has one ADC. Notation of this peripheral is ADCA.

24.2 Overview

XMEGA D3 features two Analog Comparators (AC). An Analog Comparator compares two volt-

ages, and the output indicates which input is largest. The Analog Comparator may be configured

to give interrupt requests and/or events upon several different combinations of input change.

Hysteresis can be adjusted in order to find the optimal operation for each application.

A wide range of input selection is available, both external pins and several internal signals can

be used.

The Analog Comparators are always grouped in pairs (AC0 and AC1) on each analog port. They

have identical behavior but separate control registers.

Optionally, the state of the comparator is directly available on a pin.

PORTA and has one AC pair. Notations of this peripheral is ACA.

24.3 Input Selection

The Analog comparators have a very flexible input selection and the two comparators grouped

in a pair may be used to realize a window function. One pair of analog comparators is shown in

Figure 24-1 on page 42.

• Input selection from pin

– Pin 0, 1, 2, 3, 4, 5, 6 selectable to positive input of analog comparator

– Pin 0, 1, 3, 5, 7 selectable to negative input of analog comparator

• Internal signals available on positive analog comparator inputs

• Internal signals available on negative analog comparator inputs

– 64-level scaler of the VCC, available on negative analog comparator input

– Bandgap voltage reference

24.4 Window Function

The window function is realized by connecting the external inputs of the two analog comparators

in a pair as shown in Figure 24-2.

33.1.1

rev. B

• Bandgap voltage input for the ACs cannot be changed when used for both ACs simultaneously

• Bandgap measurement with the ADC is non-functional when V_CCis below 2.7V

• ADC gain stage cannot be used for single conversions

• ADC gain stage output range is limited to 2.4V

• ADC propagation delay not correct when 8x-6x gain is used

• ADC has increased INL error for some operating conditions

• BOD will be enabled after any reset

• Writing EEPROM or Flash while reading any of them will not work

• VCC voltage scaler for AC is non-linear

• Maximum operating frequency below 1.76V is 8 MHz

• TWIE is not available

1. Bandgap voltage input for the ACs cannot be changed when used for both ACs

simultaneously

If the bandgap voltage is selected as input for one Analog Comparator (AC) and then

selected/deselected as input for the another AC, the first comparator will be affected for up

to 1 us and could potentially give a wrong comparison result.

Problem fix/Workaround

If the Bandgap is required for both ACs simultaneously, configure the input selection for both

ACs before enabling any of them.

2. Bandgap measurement with the ADC is non-functional when V_CCis below 2.7V

The ADC cannot be used to do bandgap measurements when V_CCis below 2.7V.

Problem fix/Workaround

If internal voltages must be measured when V_CCis below 2.7V, measure the internal 1.00V

reference instead of the bandgap.

3. ADC gain stage cannot be used for single conversion

The ADC gain stage will not output correct result for single conversions that is triggered and

started from software or the event system.

Problem fix/Workaround

When the gain stage is used, the ADC must be set in free running mode for correct results.

4. ADC gain stage output range is limited to 2.4 V

The amplified output of the ADC gain stage will never go above 2.4 V, hence the differential

input will only give correct output when below 2.4 V/gain. For the available gain settings, this

gives a differential input range of:

87

XMEGA D3

–

1x gain:

2x gain:

4x gain:

8x gain:

32x gain:

64x gain:

2.4

1.2

0.6

V

300 mV

150 mV

75 mV

38 mV

Problem fix/Workaround

Keep the amplified voltage output from the ADC gain stage below 2.4 V in order to get a cor-

rect result, or keep ADC voltage reference below 2.4 V.

5. ADC has increased INL error for some operating conditions

Some ADC configurations or operating condition will result in increased INL error.

In differential mode INL is increased to:

– 6 LSB for sample rates above 130 kSPS, and up to 8 LSB for 200 kSPS sample rate.

– 6 LSB for reference voltage below 1.1V when VCC is above 3.0V.

– 20 LSB for ambient temperature below 0 degree C and reference voltage below 1.3V.

In single ended mode, the INL is increased up to a factor of 3 for the conditions above.

Problem fix/Workaround

None, avoid using the ADC in the above configurations in order to prevent increased INL

error.

6. ADC propagation delay not correct when 8x-64x gain is used

The propagation delay will increase by only one ADC clock cycle for the 8x and 16x gain set-

ting, and 32x and 64x gain settings.

Problem fix/Workaround

None.

7. BOD will be enabled after any reset

If any reset source goes active, the BOD will be enabled and keep the device in reset if the

VCC voltage is below the programmed BOD level. During Power-On Reset, reset will not be

released until VCC is above the programmed BOD level even if the BOD is disabled.

Problem fix/Workaround

Do not set the BOD level higher than VCC even if the BOD is not used.

8. Writing EEPROM or Flash while reading any of them will not work

The EEPROM and Flash cannot be written while reading EEPROM or Flash, or while exe-

cuting code in Active mode.

Problem fix/Workaround

Enter IDLE sleep mode within 2.5 uS (Five 2 MHz clock cycles and 80 32 MHz clock cycles)

after starting an EEPROM or flash write operation. Wake-up source must either be

88

8134D–AVR–12/09

XMEGA D3

EEPROM ready or NVM ready interrupt. Alternatively set up a Timer/Counter to give an

overflow interrupt 7 mS after the erase or write operation has started, or 13 mS after atomic

erase-and-write operation has started, and then enter IDLE sleep mode.

9. VCC voltage scaler for AC is non-linear

The 6-bit VCC voltage scaler in the Analog Comparators is non-linear. Problem

fix/Workaround

Use external voltage input for the analog comparator if accurate voltage levels are needed.

10. Maximum operating frequency below 1.76V is 8 MHz

To ensure correct operation, the maximum operating frequency below 1.76V VCC is 8 MHz.

Problem fix/Workaround

None, avoid running the device outside this frequency and voltage limitation.

11. TWIE is not available

The TWI module on PORTE, TWIE is not available.

Problem fix/Workaround

Use the identical TWI module on PORTC, TWIC instead.
