the IICn register and the transmitting side cancels the wait state when data is written to the IICn register.
978
A wait state may be automatically generated depending on the setting of the IICCn.WTIMn bit.
Normally, the receiving side cancels the wait state when the IICCn.WRELn bit is set to 1 or when FFH is written to
The master device can also cancel the wait state via either of the following methods.
• By setting the IICCn.STTn bit to 1
• By setting the IICCn.SPTn bit to 1
