• Case 1: NACT=PUBLISH, the USART sends a response
• Case 2: NACT=SUBSCRIBE, the USART receives a response
• Case 3: NACT=IGNORE, the USART is not concerned by a response
– Wait until TXRDY is a one
– Send a byte by writing to THR.TXCHR
– Repeat the two previous steps until there is no more data to send
– Wait until CSR.LINTC is a one
– Check for LIN errors
– Wait until RXRDY is a one
– Read RHR.RXCHR
– Repeat the two previous steps until there is no more data to read
– Wait until LINTC is a one
– Check for LIN errors
– Wait until LINTC is a one
