Set the timer to start counting
TSTART bit in TRACR register ← 1

A Synch Break for timer RA is
generated.
After writing 1 to the TSTART bit,
if registers TRAPRE and TRA for
timer RA are not read or the register
settings are not changed, reading 1
from the TCSTF flag can be omitted.
Zero or one cycle of the timer RA
count source is required after timer
RA starts counting before the TCSTF
flag is set to 1.
A timer RA interrupt can be used to
end Synch Break generation.
One or two cycles of the CPU clock
are required after Synch Break
generation ends before the SBDCT
flag is set to 1.
After a Synch Break for timer RA is
generated, stop the timer count.
After writing 0 to the TSTART bit,
if registers TRAPRE and TRA for
timer RA are not read or the register
settings are not changed, reading 0
from the TCSTF flag can be omitted.
Zero or one cycle of the timer RA
count source is required after timer
RA stops counting before the TCSTF
flag is set to 0.
The Synch Field is transmitted.
The ID field is transmitted.
