RM57L843: How to synchronize PWM pulse signal between two RM57L843 chips?

Part Number: RM57L843

Hi Team,

There's an issue from the customer need your help.

For the safety function design, we used two RM57L843 microcontroller chips, and now for the safety function design we have synchronized the inside different PWM pulse signals in one MCU.

Is there a way to synchronize the PWM pulse signals between the two MCUs? Currently, we have detected that the PWM pulse signals generated by the two MCUs have varying degrees of misalignment within 1 ms.

We need to synchronize the PWM pulse signals generated by the two MCUs first and then set the phase shift as needed. Thanks.

Could you help check this case please?

Best Regards,

Ben
