TMPM330
If reception is enabled, detecting a start bit generates a start bit interrupt and starts receiving data
per byte. The interrupt is generated after a byte of data (8 bit), the EOM bit and the ACK bit are
received. The data, EOM and ACK bit are stored in a buffer.
Detecting an error during data reception causes an error interrupt, and CEC waits for the next start
bit. The received data is discarded.
