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 appropriate
for the Synch Break period.
Select the timing at which to
unmask the RXD0 input for UART0.
If the RXD0 input is chosen to be
unmasked after detection of Synch
Break, the Synch Field signal is
also input to UART0.
