37.3.15 Synchronization (FTMx_SYNC)
This register configures the PWM synchronization.
A synchronization event can perform the synchronized update of MOD, CV, and
OUTMASK registers with the value of their write buffer and the FTM counter
initialization.

Write Protection Disable
When write protection is enabled (MODE[WPDIS] = 0), write protected bits can not be written. When write
protection is disabled (MODE[WPDIS] = 1), write protected bits can be written. The WPDIS bit is the
negation of the WPEN bit. WPDIS is cleared when 1 is written to WPEN. WPDIS is set when WPEN bit is
read as a 1 and then 1 is written to WPDIS. Writing 0 to WPDIS has no effect.

Initialize the Output Channels
When a 1 is written to INIT bit the output channels are initialized according to the state of their
corresponding bit in the OUTINIT register. Writing a 0 to INIT bit has no effect.
The INIT bit is always read as 0.

Capture test mode is disabled.
Capture test mode is enabled.
No restrictions. Software and hardware triggers can be used by MOD, CV, CHnOM, and FTM counter
synchronization.
Software trigger can only be used by MOD and CV synchronization, and hardware triggers can only
be used by CHnOM and FTM counter synchronization.
Write protection is enabled.
Write protection is disabled.
Only the TPM-compatible registers (first set of registers) can be used without any restriction. Do not
use the FTM-specific registers.
All registers including the FTM-specific registers (second set of registers) are available for use with no
restrictions.
