to IIC shift register 0 (IIC0), and the transmitting side cancels the wait state when data is written to IIC0.
Transfer lines
(2) When master and slave devices both have a nine-clock wait
Remark
A wait may be automatically generated depending on the setting of bit 3 (WTIM0) of IIC control register 0 (IICC0).
Normally, the receiving side cancels the wait state when bit 5 (WREL0) of IICC0 is set to 1 or when FFH is written
The master device can also cancel the wait state via either of the following methods.
• By setting bit 1 (STT0) of IICC0 to 1
• By setting bit 0 (SPT0) of IICC0 to 1
