11.4.11.4 FTMxMODH:FTMxMODL synchronization
The FTMxMODH:L synchronization occurs when the FTMxMODH:L registers are updated with the
value of their write buffer.
The synchronization requires both bytes of FTMxMODH:L to have been written and either a hardware or
software trigger event in one of the following situations.
If REINIT = 0, then the synchronization is made on the next selected boundary cycle after an enabled
trigger event takes place. If the trigger event was a software trigger, then the SWSYNC bit is cleared on
the next selected boundary cycle
trigger enable bit (TRIGn) is cleared on the next selected boundary cycle
