LIN Frame Handling
Master Node Configuration
Write IDCHR in US_LINIR to send the header
What comes next depends on the NACT configuration:
• Write TXEN and RXEN in US_CR to enable both the transmitter and the receiver.
• Write USART_MODE in US_MR to select the LIN mode and the Master Node configuration.
• Write CD and FP in US_BRGR to configure the baud rate.
• Write NACT, PARDIS, CHKDIS, CHKTYPE, DLCM, FDIS and DLC in US_LINMR to
• Check that TXRDY in US_CSR is set to “1”
• Case 1: NACT = PUBLISH, the USART sends the response
• Case 2: NACT = SUBSCRIBE, the USART receives the response
• Case 3: NACT = IGNORE, the USART is not concerned by the response
configure the frame transfer.
– Wait until TXRDY in US_CSR rises
– Write TCHR in US_THR to send a byte
– If all the data have not been written, redo the two previous steps
– Wait until LINTC in US_CSR rises
– Check the LIN errors
– Wait until RXRDY in US_CSR rises
– Read RCHR in US_RHR
– If all the data have not been read, redo the two previous steps
– Wait until LINTC in US_CSR rises
– Check the LIN errors
– Wait until LINTC in US_CSR rises
– Check the LIN errors
