Figure 7-55 PWM Waveform Details Of eCAP APWM Mode OperationThe behavior of APWM active-high mode (APWMPOL == 0) is:
CMP = 00000000h, output low for duration of period (0% duty)
CMP = 00000001h, output high 1 cycle
CMP = 00000002h, output high 2 cycles
CMP = PERIOD, output high except for 1 cycle (<100% duty)
CMP = PERIOD+1, output high for complete period (100% duty)
CMP > PERIOD+1, output high for complete period
