A
For the hardware LIN
function, set the TIOSEL bit
in the TRAIOC register to 1.
Set the count source and
registers TRA and TRAPRE
as suitable for the Synch
Break period.
Set the BRG count source
and U0BRG register as
appropriate for the bit rate.
During master mode, the
Synch Field measurement-
completed interrupt cannot be
used.
