Hi,

The EPWM module is clocked by MAIN_SYSCLK0 /2 followed by pre-scaler etc...

Is MAIN_SYSCLK0 adjustable ?

Thanks

Hello Geoffrey,

Our PWM owner is out of office for the rest of the week. I am sending your thread to another team member who has experience with clock configuration in case they can comment. That team member will probably be on vacation the 2nd half of this week. Please ping the thread if you do not get a response by early next week.

Regards,

Nick

Hello Geoffrey,

Please look at the clock tree diagram below.

The MAIN SYS CLOCK is connected to different IP's.

So, changing the MAIN SYSCLK will impact on other IPs.

If you tell you why the customer is to change the MAIN SYSCLK, like the PWM frequency is not able to drive with the MAIN SYC CLOK frequency.

Hi Anil,

Alright so possible but not recommended as can have effect on other IPs.

Thanks
