Set the clock selection in SCSCR.
Be sure to clear bits TIE, RIE, TE,
and RE to 0.
Set the data transfer format in
SCSMR.
Write a value corresponding to the
bit rate into SCBRR. (Not
necessary if an external clock is
used.)
Wait at least one bit interval, then
set the TE bit or RE bit in SCSCR
to 1. Also set the TIE, RIE, and
REIE bits.
Setting the TE and RE bits
enables the SCIF_TXD and
SCIF_RXD pins to be used.
When transmitting, the SCIF goes
to the mark state; when receiving,
it goes to the idle state, waiting for
a start bit.
