Hi experts,
The Manuals do not describe in detail how to implement the digital loopback test for I2C.
As I understand it, I2C needs to be configured with bit 6 of I2CMDR configured, to use the loopback.
What is not clear to me is how the test data should be send and received.
(Q1)Is, after writing the data to the I2CDXR Register and immediatly reading the i2CDRR register enough or do we need to do a full data transfer with start and stop bits (and set adress to self) and wait for the data to be received in I2CDRR?
Thank you and best regards,
Max
