TRIG0 bit
system clock
selected boundary cycle
MODH:L registers
are updated if both bytes
were written
trigger 0 event
write 1 to TRIG0 bit
Figure 12-226. MODH:L synchronization when (PWMSYNC = 0), (REINIT = 0), and a
hardware trigger was used
• If PWMSYNC = 0 and REINIT = 1, then the synchronization is made on the next
enabled trigger event. If the trigger event was a software trigger, then the SWSYNC
bit is cleared. See the following figure.
