Functional Description
If (ELSnB:ELSnA = 0:0) when the counter reaches the value in the CnV register, the
CHnF bit is set and the channel (n) interrupt is generated (if CHnIE = 1), however the
channel (n) output is not controlled by FTM.
If (ELSnB:ELSnA = 1:0), then the channel (n) output is forced high at the counter
overflow (when the CNTIN register value is are loaded into the FTM counter), and it is
forced low at the channel (n) match (FTM counter = CnV) (see the following figure).
If (ELSnB:ELSnA = X:1), then the channel (n) output is forced low at the counter
overflow (when the CNTIN register value is loaded into the FTM counter), and it is
forced high at the channel (n) match (FTM counter = CnV) (see the following figure).
If (CnV = 0x0000), then the channel (n) output is a 0% duty cycle EPWM signal and
CHnF bit is not set even when there is the channel (n) match. If (CnV > MOD), then the
channel (n) output is a 100% duty cycle EPWM signal and CHnF bit is not set even when
there is the channel (n) match. Therefore, MOD must be less than 0xFFFF in order to get
a 100% duty cycle EPWM signal.

It is expected that the EPWM mode be used only with CNTIN
= 0x0000.
MOD = 0x0008
CnV = 0x0005
MOD = 0x0008
CnV = 0x0005
