Notes:
1. When rewriting the SDAO bit, write 0 to the SDAOP bit simultaneously using the MOV instruction.
2. Do not write to the SDAO bit during a transfer operation.
3. Enabled in master mode. When writing to the BBSY bit, write 0 to the SCP bit simultaneously using the MOV
4. Disabled when the clock synchronous serial format is used.

0: SCL pin is set to low
1: SCL pin is set to high
When rewriting the SDAO bit, write 0 simultaneously
When read, the content is 1.
When read
0: SDA pin output is held low
1: SDA pin output is held high
When written
0: SDA pin output is changed to low
1: SDA pin output is changed to high-impedance
When writing to the to BBSY bit, write 0 simultaneously
When read, the content is 1.
Writing 1 is invalid.
When read:
0: Bus is released
1: Bus is occupied
When written
0: Stop condition generated
1: Start condition generated
