39.4.8.1 Asymmetrical PWM
In combine mode, the control of the PWM signal first edge (when the channel (n) match
occurs, that is, FTM counter = C(n)V) is independent of the control of the PWM signal
second edge (when the channel (n+1) match occurs, that is, FTM counter = C(n+1)V).
So, combine mode allows the generation of asymmetrical PWM signals.
39.4.9 Complementary Mode
The complementary mode is selected when (FTMEN = 1), (QUADEN = 0), (DECAPEN
= 0), (COMBINE = 1), (CPWMS = 0), and (COMP = 1).
In complementary mode the channel (n+1) output is the inverse of the channel (n) output.
If (FTMEN = 1), (QUADEN = 0), (DECAPEN = 0), (COMBINE = 1), (CPWMS = 0),
and (COMP = 0), then the channel (n+1) output is the same as the channel (n) output.
