10. Increased noise when using internal 1.0V reference at low temperature
11. Configuration of PGM and CWCM not as described in XMEGA A Manual
Table 35-1.
12 PWM is not restarted properly after a fault in cycle-by-cycle mode
13. BOD will be enabled after any reset
14. BODACT fuse location is not correct
15. Sampled BOD in Active mode will cause noise when bandgap is used as reference
When operating at below 0°C and using internal 1.0V reference the RMS noise will be up
4 LSB, Peak-to-peak noise up to 25 LSB.
Problem fix/Workaround
Use averaging to remove noise.
Enabling Common Waveform Channel Mode will enable Pattern generation mode (PGM),
but not Common Waveform Channel Mode.
Enabling Pattern Generation Mode (PGM) and not Common Waveform Channel Mode
(CWCM) will enable both Pattern Generation Mode and Common Waveform Channel Mode.
Problem fix/Workaround
When the AWeX 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 AWeX I/O register to re-enable the output.
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.
The fuses for enabling BOD in active mode (BODACT) are located at FUSEBYTE2, bit 2
and 3 and not in FUSEBYTE 5 as described in the XMEGA A Manual..
Problem fix/Workaround
Access the fuses in FUSEBYTE2.
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 or Analog Comparator, the
BOD must not be set in sampled mode.
