write: Read SCSSR1 and check that
the TDRE flag is set to 1, then write
transmit data to SCTDR1 and clear
the TDRE flag to 0.
procedure: To continue serial
transmission, read 1 from the TDRE
flag to confirm that writing is possible,
then write data to SCTDR1, and then
clear the TDRE flag to 0. (Checking
and clearing of the TDRE flag is
automatic when the direct memory
access controller (DMAC) is activated
by a transmit-data-empty interrupt
(TXI) request, and data is written to
SCTDR1.)
transmission: To output a break in
serial transmission, clear the SPB0DT
bit to 0 and set the SPB0IO bit to 1 in
SCSPTR, then clear the TE bit in
SCSCR1 to 0.
