34. Errata
34.1 Atmel ATxmega32D3
34.1.1 Rev. I
 AC system status flags are only valid if AC-system is enabled
 Sampled BOD in Active mode will cause noise when bandgap is used as reference
 Temperature sensor not calibrated
1. AC system status flags are only valid if AC-system is enabled
The status flags for the ac-output are updated even though the AC is not enabled which is invalid. Also, it is not
possible to clear the AC interrupt flags without enabling either of the Analog comparators.
Problem fix/Workaround
Software should clear the AC system flags once, after enabling the AC system before using the AC system status
flags.
2. Sampled BOD in Active mode will cause noise when bandgap is used as reference
Using the BOD in sampled mode when the device is running 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 and Analog Comparator, the BOD must not be set in
sampled mode.
3. Temperature sensor not calibrated
Temperature sensor factory calibration not implemented.
Problem fix/Workaround
None
