34.1.1 Rev. I
 Temperature sensor not calibrated
1. Temperature sensor not calibrated
Temperature sensor factory calibration not implemented.
Problem fix/Workaround
None.
34.1.2 Rev. F/G/H
Not sampled.
34.1.3 Rev. E
 ADC propagation delay is not correct when gain is used
 CRC fails for Range CRC when end address is the last word address of a flash section
 AWeX fault protection restore is not done correct in Pattern Generation Mode
 Erroneous interrupt when using Timer/Counter with QDEC
 AC system status flags are only valid if AC-system is enabled
 Temperature sensor not calibrated
1. ADC propagation delay is not correct when gain is used
The propagation delay will increase by only one ADC clock cycle for all gain setting.
Problem fix/Workaround
None.
2. CRC fails for Range CRC when end address is the last word address of a flash section
If boot read lock is enabled, the range CRC cannot end on the last address of the application section. If application
table read lock is enabled, the range CRC cannot end on the last address before the application table.
Problem fix/Workaround
Ensure that the end address used in Range CRC does not end at the last address before a section with read lock
enabled. Instead, use the dedicated CRC commands for complete applications sections.
3. AWeX fault protection restore is not done correct 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.
