Timer RA generates Synch Break.
If registers TRAPRE and TRA for
timer RA do not need to be read or
the register settings do not need to be
changed after writing 1 to the
TSTART bit, the procedure for reading
TCSTF flag = 1 can be omitted.
Zero to one cycle of the timer RA
count source is required after timer
RA starts counting before the TCSTF
flag is set to 1.
The timer RA interrupt may be used
to terminate generation of Synch
Break.
One to two cycles of the CPU clock
are required after Synch Break
generation completes before the
SBDCT flag is set to 1.
After timer RA Synch Break is
generated, the timer should be made
to stop counting.
If registers TRAPRE and TRA for timer
RA do not need to be read or the
register settings do not need to be
changed after writing 0 to the TSTART
bit, the procedure for reading TCSTF
flag = 0 can be omitted.
Zero to one cycle of the timer RA count
source is required after timer RA stops
counting before the TCSTF flag is set
to 0.
Transmit the Synch Field.
Transmit the ID field.
