39.1.1 Rev. G
AWeX fault protection restore is not done correct in Pattern Generation Mode
1.
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.
