LIN Client Transmitter

When the Client process is a transmitter, software performs the following tasks in the order shown:

The UART accumulates the checksum as each byte is written to UxTXB. After the last byte is written, the UART stores the calculated checksum in the UxTXCHK register and transmits the inverted result as the last byte in the response.

The UxTXIF flag is disabled when the number of bytes specified by the value in the UxP2 register have been written. Any writes to UxTXB that exceed the UxP2 count will be ignored and set the TXWRE flag.
