ePWM is taking extra 20uSec to toggle the pin

[Basavanagouda1]

Hi All,

We are using input capture module in our code the monitor the input pulses, based on the pulses we are calculating PWM period to turn on the pin High and Low.

We have set the PWM period but we observed the 20usec mismatch in the output. We have provide the proper clock and my set period value,May i know how we can figure the root cause for it.

we have toggle a gpio before and after the epwm_lld_enable_channel3 function call, it is taking around 10usec time to execute this line. Is this intended behavior or have we missed any thing to set?

Please help us ASAP to solve this issue, its become a showstopper.

Thanks.

Basava.
