41.5.23 Initialization Trigger
Initialization trigger allows FTM to generate a trigger in some specific points of FTM
counter cycle. This feature is controlled by the bits INITTRIGEN and ITRIGR. The
INITTRIGEN bit enables the initialization trigger generation and the ITRIGR bit selects
when the initialization trigger is generated.
If INITTRIGEN = 1 and ITRIGR = 1, then the initialization trigger is generated when
FTM counter reaches a reload point according to the frequency of the reload
opportunities (
Reload Points ).
NOTE
For this configuration of initilization trigger and in CPWM
mode, the bits CNTMAX and CNTMIN select where the
initialization trigger is generated.
If INITTRIGEN = 1 and ITRIGR = 0, then the initialization trigger is generated when
FTM counter is updated with the CNTIN register value. See the cases below.
1. When FTM counter is updated with CNTIN register value automatically.
