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 write transfer request.

• 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
• Write NACT, PARDIS, CHKDIS, CHKTYPE, DLCM and DLC in US_LINMR to configure the
frame transfer.
