written to the IICA shift register (IICA), and the transmitting side cancels the wait state when data is written to the IICA
register.

(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 (WTIM) of IICA control register 0 (IICCTL0).
Normally, the receiving side cancels the wait state when bit 5 (WREL) of the IICCTL0 register is set to 1 or when FFH is
The master device can also cancel the wait state via either of the following methods.
• By setting bit 1 (STT) of the IICCTL0 register to 1
• By setting bit 0 (SPT) of the IICCTL0 register to 1
