When w riting to the SDAO bit, w rite 0 to the SDAOP bit using the MOV instruction simultaneously.
Do not w rite during transfer operation.
This bit is enabled in master mode. When w rite to the BBSY bit, w rite 0 to the SCP bit using the MOV instruction
simultaneously. Execute the same w ay w hen the start condition is regenerating.
This bit is disabled w hen the clock synchronous serial format is used.
