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?
Hi, could you please elaborate the question more in detail? I am not sure if I understand you. Thanks
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.
OK
You don't need to detect it. Use TFFF and/or RFDF flags to find out wheter it is needed to push/drain the data.
