34.1.3 rev. A/B

XMEGA D4

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

• VCC voltage scaler for AC is non-linear

• ADC gain stage cannot be used for single conversion

• ADC has increased INL error for some operating conditions

• ADC gain stage output range is limited to 2.4 V

• ADC Event on compare match non-functional

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

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

• Accuracy lost on first three samples after switching input to ADC gain stage

• Configuration of PGM and CWCM not as described in XMEGA D Manual

• PWM is not restarted properly after a fault in cycle-by-cycle mode

• BOD: BOD will be enabled at any reset

• Sampled BOD in Active mode will cause noise when bandgap is used as reference

• EEPROM page buffer always written when NVM DATA0 is written

• Pending full asynchronous pin change interrupts will not wake the device

• Pin configuration does not affect Analog Comparator Output

• NMI Flag for Crystal Oscillator Failure automatically cleared

• Flash Power Reduction Mode can not be enabled when entering sleep

• Crystal start-up time required after power-save even if crystal is source for RTC

• RTC Counter value not correctly read after sleep

• Pending asynchronous RTC-interrupts will not wake up device

• TWI Transmit collision flag not cleared on repeated start

• Clearing TWI Stop Interrupt Flag may lock the bus

• TWI START condition at bus timeout will cause transaction to be dropped

• TWI Data Interrupt Flag (DIF) erroneously read as set

• WDR instruction inside closed window will not issue reset

• Inverted I/O enable does not affect Analog Comparator Output

• TWIE is not available

• CRC generator module is not available

• ADC 1/x gain setting and VCC/2 reference setting is not available

• TOSC alternate pin locations is not available

• TWI SDAHOLD time configuration is not available

• Timer/Counter 2 is not available

• HIRES+ option is not available

• Alternate pin locations for digital peripherals are not available

• XOSCPWR high drive option for external crystal is not available

• PLL divide by two option is not available

• Real Time Counter non-prescaled 32 kHZ clock options are not available

• PLL lock detection failure function is not available

• Non available functions and options
