XMEGA B3 [DATASHEET]
8074D–AVR–08/2013
38.
Errata
38.1
ATxmega64B3, ATxmega128B3
38.1.1 Rev. C
Device revision number
AWeX fault protection restore is not done correct in Pattern Generation Mode
1. Device revision number is unchanged between rev. B and rev. C
2. AWeX fault protection restore is not done correctly in Pattern Generation Mode
When a fault is detected the OUTOVEN register is cleared, and when fault condition is cleared, OUTOVEN is
restored according to the corresponding enabled DTI channels. For Common Waveform Channel Mode (CWCM),
this has no effect as the OUTOVEN is correct after restoring from fault. For Pattern Generation Mode (PGM),
OUTOVEN should instead have been restored according to the DTILSBUF register.
Problem fix/Workaround
For CWCM no workaround is required.
For PGM in latched mode, disable the DTI channels before returning from the fault condition. Then, set correct
OUTOVEN value and enable the DTI channels, before the direction (DIR) register is written to enable the correct
outputs again.
For PGM in cycle-by-cycle mode there is no workaround.
38.1.2 Rev. B
Not sampled.
38.1.3 Rev. A
Power down consumption
ADC conversion error when x0.5 gain is used
1. Power Down consumption
After reset, when system enters in power down or when ADC is disabled, extra power consumption is drawn.
Problem fix/Workaround
Set ADC to a configuration different from differential mode.
2. ADC conversion error when x0.5 gain is used
When the gain is set to x0.5, the conversion result is similar to the gain setting x1.
Problem fix/Workaround
There is no workaround.
