Hardware LIN measures the Synch
Field.
The interrupt of timer RA may be
used (the SBDCT flag is set when
the timer RA counter underflows
upon reaching the terminal count).
When the SBE bit in the LINCR
register is set to 1 (unmasked after
Synch Field measurement is
completed), timer RA may be used
in timer mode after the SFDCT bit
in the LINST register is set to 1.
Set a communication rate based on
the Synch Field measurement
result.
Communication via UART0
(The SBDCT flag is set when the
timer RA counter underflows upon
reaching the terminal count.)
