In the case of I
• By writing data to the IICn register
• By setting the IICCn.WRELn bit to 1 (wait state cancellation)
• By setting the IICCn.STTn bit to 1 (start condition generation)
• By setting the IICCn.SPTn bit to 1 (stop condition generation)
If any of these wait state cancellation actions is performed, I
When canceling the wait state and sending data (including address), write data to the IICn register.
To receive data after canceling the wait state, or to complete data transmission, set the WRELn bit to 1.
To generate a restart condition after canceling the wait state, set the STTn bit to 1.
To generate a stop condition after canceling the wait state, set the SPTn bit to 1.
Execute cancellation only once for each wait state.
For example, if data is written to the IICn register following wait state cancellation by setting the WRELn bit to 1, a
Even in other operations, if communication is stopped halfway, clearing the IICCn.IICEn bit to 0 will stop
