My work target:
At the middle point of FlexPWM0_B2 to trigger CTU to trigger the ADC commands.
Method1: Set PWM0_B2 VAL0 output trigger to CTU
Issues: I found CTU trigger is not in the middle of FlexPWM0_B2 (No CTU TCR0V=0)
Question: Why VAL0 output trigger is not in the middle of FlexPWM?
Method2: Set PWM0_B2 VAL4 output trigger to CTU
When I set VAL4 output trigger to CTU, I found the TCR0V needed to be varied with PWM period and dutycyle.
So how to set TCR0V according to PWM prescaler,PWM period and dutycyle and CTU prescaler? For example,PWM frequency 20Khz,50% duty cyle.
