Is it possibe to do: Fractional average duty for PWM.
I work with CYTVII-B-E-1M-176CPU ( CYT2B78CAAAES uC )
Example:
Controller period: 200us
PWM switching period: 5us (40 switchings during single controller period)
Is it possible to reach fractional duty (example 300.5) on hardware peripherials only, by changing compare value by 1 from pulse to pulse.
Example 300, 301, 300, 301, 300, 301, etc. (20 switchings with CC of 300 and 300 switching with CC of 301).
Mean value PWM: 300,5
