TMS320F280025: Any limitation with CMPC/D as zero?

Part Number: TMS320F280025


Dear Champs,

I am asking this for our customer.

1) As I remember, CMPA and CMPB has limitation when using it from 0 to non-zero for PWM output (usually 0 or 100% duty), right? Is this still valid on F28002x?

2) The above means they are used for PWM generation. But if they are used for PWM SOC to trigger ADC or used for ISR, is there any similar limitation, say from 0 to non-zero?

3) Likewise, for CMPC and CMPD used only for EPWM SOC or interrupt, do they have similar or any limitation?
