Fractional delay logic of eFlexPWM of MC56F82748

Question asked by Chuangang Xu on Dec 12, 2016

Hi, 

I'm debugging the fractional delay loigc of eFlexPWM of MC56F82748 using P&E mode. The configuration is as attached.

In theory, the duty cycle of PWM45 is closed to PWM23. However the duty cycle of PWM45 is neither closed to PWM23 when PWM_VALUE3 = 250 nor closed to that when PWM_VALUE3 = 249. Actually the falling edge of PWM45 is in the middle of PWM23 when PWM_VALUE3 equals 249 and 250. Is there any configuration wrong i neglected?Attached is the project i am debugging. thanks.
