   @davids5 I also had the same question regarding how to initiate the bus clear process. Surprisingly, the datasheet does not provide any explanation on how to do that nor any of the I2C registers have anything related bus clear to my understanding. I am presuming that the MCU somehow detects that the SDA line is stuck to low and automatically initiates the Bus Clear process.
