Functional Description
39.4.5 Output Compare Mode
The output compare mode is selected when (DECAPEN = 0), (COMBINE = 0),
(CPWMS = 0), and (MSnB:MSnA = 0:1).
In output compare mode, the FTM can generate timed pulses with programmable
position, polarity, duration, and frequency. When the counter matches the value in the
CnV register of an output compare channel, the channel (n) output can be set, cleared, or
toggled.
When a channel is initially configured to toggle mode, the previous value of the channel
output is held until the first output compare event occurs.
The CHnF bit is set and the channel (n) interrupt is generated (if CHnIE = 1) at the
channel (n) match (FTM counter = CnV).
