5. Refer to 20.6.1 Access of Registers Associated w ith IIC for the access of registers associated w ith IIC.
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.

0 : SCL pin is set to “L”
1 : SCL pin is set to “H”
When rew rite to SDAO bit, w rite “0” simultaneously
When read, its content is “1”.
When read
0 : SDA pin output is held “L”
1 : SDA pin output is held “H”
When w rite
0 : SDA pin output is changed to “L”
1 : SDA pin output is changed to high-impedance
When w rite to BBSY bit, w rite “0” simultaneously
When read, its content is “1”.
Writing “1” is disabled.
When read
0 : Bus is in released state
1 : Bus is in occupied state
When w rite
0 : Generates stop condition
1 : Generates start condition
