Header
This is identical to the master node configuration above, except for:
IMPORTANT : if NACT=PUBLISH, and this field is already correct, the LINMR register must still
be written with this value in order to set TXRDY, and to request the corresponding Peripheral
DMA Controller write transfer.
The different NACT settings result in the same procedure as for the master node, see

Header
• LIN mode selected in MR.MODE is slave
• When the baud rate is configured, wait until CSR.LINID is a one, then;
• Check for LINISFE and LINPE errors, clear errors and LINIDby writing a one to RSTSTA
• Read IDCHR
• Configure the frame transfer by writing to NACT, PARDIS, CHKDIS, CHKTYPE, DLCM, and
DLC in LINMR
