An ACK error interrupt occurs when an ACK response does not conform to the configuration
When the ACK error interrupt occurs, the CECTSTAT <CECTIACK> bit is set.
The ACK error is detected in the following cases.
A transmit buffer underrun error is caused by the following sequence.
1. Data in the transmit buffer is transmit to the shift register.
2. An interrupt occurs.
3. A byte of data is transmitted.
4. No data is set to the transmit buffer before starting transmission of a byte of subsequent data.
When an underrun error occurs, the CECTSTAT <CECTIUR> bit is set.
If interrupt factors of the ACK error and transmit buffer underrun are detected at the end of
To stop transmission, send data including the EOM bit that indicates “1”. This generates a transmit
