Hello,

Is there any way to clear ICDXR and ICXSR on i2c normal operation?

It looks dummy data exist on ICXSR so the dummy data are sent first next transaction.

I need to reset ICXSR if it is possible.

Hi,

From what i understand from the i2c user guide (www.ti.com/.../sprugv3.pdf), you need to reset the whole module... Set the ICS bit from ICMDR.

Can you share what dummy data does your device transmits at the beginning of eacg transfer?

Best Regards,
Yourdan
