Figure 39-182. Example of the Output Compare mode when the match sets the channel
output
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 modified and controlled by FTM.
39.5.6 Edge-Aligned PWM (EPWM) mode
The Edge-Aligned mode is selected when:
• QUADEN = 0
