JTAG revision
AWeX fault protection restore is not done correct in Pattern Generation Mode
Power Down consumption
ADC convertion error when x0.5 gain is used
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 condi-
tion. 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
After reset, when system enters in power down or when ADC is disabled, extra power con-
sumption is drawn.
Problem fix/Workaround
Set ADC to a configuration different from differential mode.
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.
