Notes 1. To generate a start condition, set WTIM0 to 1 and change the timing for generating the INTIIC0
Remark
Remark
1: IICS0 = 1000×110B
2: IICS0 = 1000×000B (Sets WTIM0 to 1)
3: IICS0 = 1000××00B (Clears WTIM0 to 0
4: IICS0 = 1000×110B
5: IICS0 = 1000×000B (Sets WTIM0 to 1)
6: IICS0 = 1000××00B (Sets SPT0 to 1)
7: IICS0 = 00000001B

1: IICS0 = 1000×110B
2: IICS0 = 1000××00B (Sets STT0 to 1)
3: IICS0 = 1000×110B
4: IICS0 = 1000××00B (Sets SPT0 to 1)
5: IICS0 = 00000001B
