5 8135j?avr?12/10 xmega d4 3. overview the atmel ? avr ? xmega ? d4 is a family of low power, high performance and peripheral rich cmos 8/16-bit microcontrollers based on the avr ? enhanced risc architecture. by executing powerful instructions in a single clock cycle, the xmega d4 achieves throughputs approaching 1 million instructions per second (mips) per mhz allowing the system designer to optimize power consumption 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 instructi on, executed in one clock cycle. the resulting architecture is more code efficient while achi eving throughputs many times faster than conven- tional single-accumula tor or cisc based microcontrollers. the xmega d4 devices provide the following features: in-system programmable flash with read- w hile- w rite capabilities, internal eeprom and sram, four-channel event system, pro- grammable multi-level interrupt controller, 34 general purpose i/o lines, 16-bit real time counter (rtc), four flexible 16-bit timer/counters with compare modes and p w m, two usarts, two two- w ire interfaces (t w is), two serial peripheral in terfaces (spis), one twelve- channel 12-bit adc with optional differential input with programmable gain, two analog compar- ators with window mode, programmable w atchdog 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 d4 devices have five software selectable power saving modes. the idle mode stops the cpu while allowing the sram, event sy stem, 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 t w i 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 whil e 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 os cillator and the asynch ronous timer continue to run. to further reduce power consumption, the peripheral clock to each individual peripheral can optionally be stopped in active mode and in idle sleep mode. the device is manufactured using atmel's high-density nonvolatile memory technology. the pro- gram flash memory can be reprogrammed in-sys tem 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- w hile- w rite operation. by combining an 8/16-bit risc cpu with in-system self-programmable flash, the atmel xmega d4 is a powerful microcon- troller family that provides a highly flexible and cost effective solution for many embedded applications. the xmega d4 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.

9 8135j?avr?12/10 xmega d4 this concept enables instructions to be executed in every clock cycle. the program memory is in-system re-programmable flash memory. 6.3 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 ar ithmetic 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-b it 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. 6.4 alu - arithmetic logic unit the high performance arithmetic logic unit (a lu) supports arithmetic and logic operations between registers or between a constant and a regi ster. single register operations can also be executed. w ithin 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 w hen 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 sr am. 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.

11 8135j?avr?12/10 xmega d4 7.3 in-system programmable flash program memory the xmega d4 devices contain on-chip in-system programmable flash memory for program storage, see figure 7-1 on page 11 . 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 restrict ions on write or read/write operations. the store program memory (spm) instruction must reside in the boot section when used to write to the flash memory. a third section inside the applicat ion 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. the application table section and boot sect ion can also be used for general application software. figure 7-1. flash program memory (hexadecimal address) word address 0 application section (128k/64 kb/32 kb/16 kb) ... efff / 77ff / 37ff / 17ff f000 / 7800 / 3800 / 1800 application table section (4 kb/4 kb/4 kb/4 kb) ffff / 7fff / 3fff / 1fff 10000 / 8000 / 4000 / 2000 boot section (8 kb/4 kb/4 kb/4 kb) 10fff / 87ff / 47ff / 27ff
12 8135j?avr?12/10 xmega d4 7.4 data memory the data memory cont aints the i/o memory, eeprom and sr am memories, all within one lin- ear address space, see figure 7-2 on page 12 . to simplify development, the memory map for all devices in the family is identical and with empt y, reserved memory space for smaller devices. 7.4.1 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-acce ssible 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 d4 is shown in the ?periph- eral module address map? on page 50 . 7.4.2 sram data memory the xmega d4 devices have internal sram memory for data storage. figure 7-2. data memory map (hexadecimal address) byte address atxmega64d4 byte address ATXMEGA32D4 byte address atxmega16d4 0 i/o registers (4kb) 0 i/o registers (4kb) 0 i/o registers (4kb) fff fff fff 1000 eeprom (2k) 1000 eeprom (1 kb) 1000 eeprom (1 kb) 17ff 13ff 13ff reserved reserved reserved 2000 internal sram (4 kb) 2000 internal sram (4 kb) 2000 internal sram (2 kb) 2fff 2fff 27ff byte address atxmega128d4 0 i/o registers (4 kb) fff 1000 eeprom (2k) 17ff reserved 2000 internal sram (8k) 3fff
13 8135j?avr?12/10 xmega d4 7.4.3 eeprom data memory the xmega d4 devices have internal eeprom me mory 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. 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 dev ice 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 a4 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. table 7-1. device id bytes for xmega d4 devices. 7.6 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. 7.7 flash and eeprom page size the flash program memory and eeprom data memory are organize d 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) give the page number and the least significant address bits (f w ord) give the word in the page. device device id bytes byte 2 byte 1 byte 0 atxmega16d4 42 94 1e ATXMEGA32D4 42 95 1e atxmega64d4 47 96 1e atxmega128d4 47 97 1e

16 8135j?avr?12/10 xmega d4 figure 8-1. event system block diagram the event routing network can directly connect together adcs, analog comparators (acx), 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 eight multiplexers where each can be configured in software to select which event to be routed into that event channel. all eight event channels are connected to the peripherals that can use events, and each of these peripherals can be co nfigured to use events from one or more event channels to automatically trigger a software selectable action. adcx event routing network portx cpu acx rtc t/cxn ircom clk sys

20 8135j?avr?12/10 xmega d4 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 xmega provides various sleep modes and software controlled clock gating in order to tailor power consumption to the application's requirement. sleep modes enables the microcontroller to shut down unused modules to save power. w hen the device enters sleep mode, program exe- cution is stopped and interrupts or reset is used to wake the device again. the individual clock to unused peripherals can be stopped during normal oper ation or in sleep, enabling a much more fine tuned power management than sleep modes alone 10.3 sleep modes sleep modes are used to shut down modules and clock domains in the microcontroller in order to save power. xmega ha s five different sleep modes. a de dicated sleep instruction (sleep) is available to enter sleep. before executing sleep, the selected sleep mode to enter must be configured. the available interrupt wake-up sources is dependent on the selected sleep mode. w hen an enabled interrupt occurs the device will wake up and ex ecute the interr upt service rou- tine before continuing normal program execution from the first instruction after the sleep instruction. if other higher priority interrupts are pending when the wake-up occurs, their interrupt service routines will be executed a ccording to their priority before the interrupt serv ice routine for the wake-up interrupt is executed . after wake-up th e cpu is halted for four cycles before execu- tion starts. 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 operatio n of asynchronous modules only. the only inter- rupts that can wake up the mcu are the two w ire interface address match interrupts, and asynchronous port interrupts. 10.3.3 power-save mode power-save mode is identical to power-down, with one exception: if the real time counter (rtc) is enabled, it will keep running during sl eep and the device can also wake up from either rtc overflow or compare match interrupt.
21 8135j?avr?12/10 xmega d4 10.3.4 standby mode standby mode is identical to power-down with the exception that all enabled system clock sources are kept running, while the cpu, periph eral and rtc clocks are stopped. this reduces the wake-up time when external crystals or resonators are used. 10.3.5 extended standby mode extended standby mode is identical to power-sav e mode with the exception that all enabled system clock sources are kept ru nning while the cpu and periph eral clocks are stopped. this reduces the wake-up time when external crystals or resonators are used.
22 8135j?avr?12/10 xmega d4 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, dedica ted 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 power-on reset the mcu is reset when the supp ly voltage vcc is below the po wer-on reset threshold voltage. 11.3.2 external reset the mcu is reset when a low leve l is present on the reset pin. 11.3.3 watchdog reset the mcu is reset when the w atchdog timer period expires and the w atchdog reset is enabled. the w atchdog timer runs from a dedicated oscillator independent of the system clock. for more details see ? w dt - w atchdog timer? on page 23 . 11.3.4 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.
23 8135j?avr?12/10 xmega d4 11.3.5 pdi reset the mcu can be reset through the program and debug interface (pdi). 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 th e 32 khz ultra low power oscillator ? configuration lock to prevent unwanted changes 12.2 overview the xmega d4 has a w atchdog timer ( w dt). the w dt will run continuously when turned on and if the w atchdog timer is not reset within a software configurable time-out period, the micro- controller will be reset. the w atchdog reset ( w dr) instruction must be ru n by software to reset the w dt, and prevent microcontroller reset. the w dt has a w indow mode. in this mode the w dr 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 w dr instruction is not executed inside t he window limits, the microcontroller will be reset. a protection mechanism using a timed write se quence is implemented in order to prevent unwanted enabling, disabling or change of w dt settings. for maximum safety, the w dt 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 w dt.

32 8135j?avr?12/10 xmega d4 16. awex - advanced waveform extension 16.1 features ? output with complementary output from each capture channel ? four dead time insertion (dti) un its, 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 w aveform extension (a w ex) provides extra features to the timer/counter in w aveform generation ( w g) modes. the a w ex enables easy and safe implementation of for example, advanced motor control (ac, bldc, sr , and stepper) and power control applications. any w g output from a timer/counter 0 is split into a complimentary pair of outputs when any a w ex 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 w g 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. w hen the pattern generator unit is enabled, the dti unit is bypassed. the fault protection unit is connected to the ev ent system. this enables any event to trigger a fault condition that will disable the a w ex output. several event channels can be used to trigger fault on several different conditions. the a w ex is available for tcc0. the notation of this is a w exc.
33 8135j?avr?12/10 xmega d4 17. hi-res - high r esolution 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 enable d 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. w hen enabled for a timer/counter, the fast peripheral clock running at four times the cpu clock speed will be as input to th e timer/counter. the high resolution extension can also be used when an a w ex is enabled and used with a timer/counter. xmega d4 devices have one hi-res extension that can be enabled for each timer/counter on portc. the notation of this is hiresc.

91 8135j?avr?12/10 xmega d4 figure 33-1. analog comparator voltage scaler vs. scalefac t = 25c problem fix/workaround use external voltage input for the analog comparator if accurate voltage levels are needed 3. adc gain stage cannot be used for single conversion the adc gain stage will no t output correct result for singl e conversion that is triggered and started from software or event system. problem fix/workaround w hen the gain stage is used, the adc must be set in free running mode for correct results. 4. adc has increased inl error for some operating conditions some adc configurations or operating co ndition will result in increased inl error. in signed mode inl is increased to: ? 6lsb for sample rates above 130ksps, and up to 8lsb for 200ksps sample rate. ? 6lsb for reference voltage below 1.1v when vcc is above 3.0v. ? 20lsb for ambient temperature below 0 degree c and reference voltage below 1.3v. in unsigned mode, the inl error cannot be guaranteed, and this mode should not be used. problem fix/workaround none, avoid using the adc in the above configurations in order to prevent increased inl error. use the adc in signed mode also for single ended measurements. 5. adc gain stage output range is limited to 2.4 v the amplified out put of the adc gain stage will never go above 2.4 v, hence the differential input will only give corr ect output when below 2.4 v/gain. for the ava ilable gain settings, this gives a differential input range of: 3.3 v 2.7 v 1. 8 v 0 0.5 1 1.5 2 2.5 3 3.5 0 5 10 15 20 25 30 35 40 45 50 55 60 65 scalefac v scale [ v ]
92 8135j?avr?12/10 xmega d4 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. 6. adc event on compare match non-functional adc signalling event will be given at every conversion complete even if interr upt mode (int- mode) is set to belo w or above. problem fix/workaround enable and use interrupt on compare match when using the compare function. 7. adc propagation delay is not correct when 8x -64x gain is used the propagation dela y will increase by only one adc cloc k cycle for 8x and 16x gain setting, and 32x and 64x gain settings. problem fix/workaround none 8. bandgap measurement with the adc is non-functional when vcc is below 2.7v the adc can not be used to do bandgap measurements when vcc is below 2.7v. problem fix/workaround none. 9. accuracy lost on first three samples after switching input to adc gain stage due to memory effect in the adc gain stage, the first three samples after changing input channel must be disregarded to achieve 12-bit accuracy. problem fix/workaround run three adc conversions and discard these results after changing input channels to adc gain stage. 10. configuration of pgm and cwcm not as described in xmega a manual enabling common w aveform channel mode will enable pattern generation mode (pgm), but not common w aveform channel mode. enabling pattern generation mode (pgm) and not common w aveform channel mode (c w cm) will enable both pattern ge neration mode and common w aveform channel mode. ? 1x gain: 2.4 v ? 2x gain: 1.2 v ? 4x gain: 0.6 v ? 8x gain: 300 mv ? 16x gain: 150 mv ? 32x gain: 75 mv ? 64x gain: 38 mv
93 8135j?avr?12/10 xmega d4 problem fix/workaround 11. pwm is not restarted properly after a fault in cycle-by-cycle mode w hen the a w ex fault restore mode is set to cycle- by-cycle, the waveform output will not return to normal operation at first update after fault condition is no longer present. problem fix/workaround do a write to any a w ex i/o register to re-enable the output. 12. bod will be enabled after any reset if any reset source go es active, the bod will be enabled and keep the device in reset if the vcc voltage is below the prog rammed bod level. during powe r-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. 13. sampled bod in active mode will cause noise when bandgap is used as reference using the bod in sample d mode when the device is runnin g in active or idle mode will add noise on the bandgap reference for adc, dac and analog comparator. problem fix/workaround if the bandgap is used as reference for either the adc, dac or the analog comparator, the bod must not be set in sampled mode. 14. eeprom page buffer always written when nvm data0 is written if the eeprom is memory mapp ed, writing to nvm data0 will corrupt data in the eeprom page buffer. problem fix/workaround before writing to nvm data0, for exampl e when doing software crc or flash page buffer write, check if eeprom page buff er active loading flag (eeloa d) is set. do not write nvm data0 when eeload is set. 15. pending full asynchronous pin change interrupts will not wake the device any full asynchronous pin-change interrupt from pin 2, on any port, that is pending when the sleep instruction is executed, will be ignor ed until the device is woken from another source or the source triggers again. this applies w hen entering all sleep modes where the system clock is stopped. problem fix/workaround none. 16. pin configuration does not affect analog comparator output the output/pull and inverted pin configuration does not affect the analog comparator output. table 33-1. configure p w m and c w cm according to this table: pgm cwcm description 0 0 pgm and c w cm disabled 0 1 pgm enabled 1 0 pgm and c w cm enabled 1 1 pgm enabled
94 8135j?avr?12/10 xmega d4 problem fix/workaround none for output/pull configuration. for inverted i/o, configure the analog comparator to give an inverted result (i.e. connect positive input to the negative ac input and vice versa), or use and external inverter to change polarity of analog comparator output. 17. nmi flag for crystal oscillator failure automatically cleared nmi flag for crystal oscillator failure (xoscf dif) will be automatically cleared when exe- cuting the nmi interrupt handler. problem fix/workaround this device revision has only one nmi interrupt source, so checking the interrupt source in software is not required. 18. flash power reduction mode can not be enabled when entering sleep if flash power reduction mode is enabled when entering power-save or extended standby sleep mode, the device will only wake up on every fourth wake -up request. if flash power reduction mode is enabled wh en entering idle sleep mode, th e wake-up time will vary with up to 16 cpu clock cycles. problem fix/workaround disable flash power reduction mode before entering sleep mode. 19. crystal start-up time required after power-save even if crystal is source for rtc even if 32.768 khz crystal is used for rtc duri ng sleep, the clock fr om the crystal will not be ready for the system before th e specified start-up time. see "xoscsel[3:0]: crystal oscilla- tor selection" in xmega a manual. if bod is us ed in active mode, the bod will be on during this period (0.5s). problem fix/workaround if faster start-up is required , go to sleep with internal oscillator as system clock. 20. rtc counter value not correctly read after sleep if the rtc is set to wake up the device on rt c overflow and bit 0 of rtc cnt is identical to bit 0 of rtc per as the device is entering sleep, the value in the rtc count register can not be read correctly within the first prescaled rtc clock cycle after wakeup. the value read will be the same as the value in the register when entering sleep. the same applies if rtc compare match is used as wake-up source. problem fix/workaround w ait at least one prescaled rtc clock cycle before reading the rtc cnt value. 21. pending asynchronous rtc-inte rrupts will not wa ke up device asynchronous interrupts from the real-time-counter that is pending when the sleep instruction is executed, will be ignored until the device is woken from another source or the source triggers again. problem fix/workaround none. 22. twi transmit collision flag not cleared on repeated start the t w i transmit collision flag should be automatically cleared on start and repeated start, but is only cleared on start.
95 8135j?avr?12/10 xmega d4 problem fix/workaround clear the flag in software after address interrupt. 23. clearing twi stop interrupt flag may lock the bus if software clears the stop interrupt flag (apif) on the same peripheral clock cycle as the hardware sets this flag due to a new address received, clkhold is not cleared and the scl line is not released. this will lock the bus. problem fix/workaround check if the bus state is idle. if this is the case, it is safe to clear apif. if the bus state is not idle, wait for the scl pin to be low before clearing apif. code: /* only clear the interrupt flag if within a "safe zone". */ while ( /* bus not idle: */ ((comms_twi.master.status & twi_master_busstate_gm) != twi_master_busstate_idle_gc)) && /* scl not held by slave: */ !(comms_twi.slave.status & twi_slave_clkhold_bm) ) { /* ensure that the scl line is low */ if ( !(comms_port.in & pin1_bm) ) if ( !(comms_port.in & pin1_bm) ) break; } /* check for an pending address match interrupt */ if ( !(comms_twi.slave.status & twi_slave_clkhold_bm) ) { /* safely clear interrupt flag */ comms_twi.slave.status |= (uint8_t)twi_slave_apif_bm; } 24. twi start condition at bus timeout will cause transaction to be dropped if bus timeout is enabled and a timeout occurs on the same peripheral clock cycle as a start is detected, the tr ansaction will be dropped. problem fix/workaround none. 25. twi data interrupt flag erroneously read as set w hen issuing the t w i slave response command cmd=0b11, it takes 1 peripheral clock cycle to clear the data interrupt flag (dif). a read of dif directly after issuing the command will show the dif still set. problem fix/workaround add one nop instruction before checking dif. 26. wdr instruction inside closed window will not issue reset w hen a w dr instruction is execute within one ulp clock cycle after updating the window control register, the counter can be cleared without giving a system reset.
96 8135j?avr?12/10 xmega d4 problem fix/workaround w ait at least one ulp clock cycle before executing a w dr instruction. 27. twie is not available the t w i module on porte, t w ie is not available problem fix/workaround use the identical t w i module on portc, t w ic instead. 28. inverted i/o enable does not affect analog comparator output the inverted i/o pin function does not affect the analog comparator output function problem fix/workaround configure the analog comparator setup to give an inverted result, or use an external inverter to change polarity of analog comparator output.
