Transmission starts anytime if bus is free for specified bit cycles.
the shift register, and data transmission is started. When CEC starts transmitting the first bit of a byte
of data, a transmit interrupt is generated. It sets the CECTSTAT <CECTISTA> bit. Subsequent to the
transmit interrupt, a byte of next data can be set to the transmit buffer.
This is the end of a byte of data transmission.

determined as an error. If this bit is not set, the ACK response of logical “1” is determined as an error.
(Note)
Transmission is ready by setting the CECTEN <CECTEN> bit to start transmission after setting the
The <CECTEN> bit is never cleared to “0” until a transmit completion interrupt or an error interrupt
Next to the setting for starting transmission, CEC checks if a bus is free. If “1” is sampled as a CEC
After transmitting a start bit, a byte of data and the EOM data that are set in the buffer are sent to
Then 8 bit data, the EOM bit and the ACK bit are transmitted, and the ACK response is checked.
Data transfer continues in the above sequence until “1” is set to the EOM bit.
If “1” is set to the EOM, a transmit completion interrupt is generated subsequent to the ACK bit
A criterion of the ACK error differs depending on the CECTCR <CECBRD> bit.
If this bit is set, broadcast message is transmitted, and the ACK response of logical “0” is
Changing the configurations of the CECTCR register during transmission or
reception may harm its proper operation. Be careful if you change it during
transmission.
