Slave Node Configuration
Break
Write NACT, PARDIS, CHKDIS, CHKTYPE, DLCM and DLC in US_LINMR to configure the
frame transfer.
IMPORTANT: if the NACT configuration for this frame is PUBLISH, the US_LINMR register,
must be write with NACT = PUBLISH even if this field is already correctly configured, in order to
set the TXREADY flag and the corresponding PDC write transfer request.
What comes next depends on the NACT configuration:
Header
Synch
• 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 Slave Node configuration.
• Write CD and FP in US_BRGR to configure the baud rate.
• Wait until LINID in US_CSR rises
• Check LINISFE and LINPE errors
• Read IDCHR in US_RHR
• Case 1: NACT = PUBLISH, the LIN controller sends the response
• Case 2: NACT = SUBSCRIBE, the USART receives the response
• Case 3: NACT = IGNORE, the USART is not concerned by the response
– 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
