Some devices may interpret SPI data after CS from low(active) to high.So TCF in SR register can't indicate if the whole SPI process has completed.
I have to add a time filter although it's not a good solution, so is there any other solution or relevant flag to detect CS signal?
The transmission is considered successful only after CS from LOW to HIGH for this chip. In practice, I want to detect CS signal to judge whether the data received by device is actually processed.
Thanks for your reply.
