AM3359: DMTimer synchronization

Part Number: AM3359

Can the DMTimer synchronize between the modules (DMTimer[2-7])?

Our customer want to use DMTimer[4-7] for four pulse-width modulation (PORTIMERPWM) outputs which are synchronized.

If so, how are the modules configured?

Best regards,

Hi,

I don't believe this is possible to be done across several timers. The AM335x has an ePWM module inside the PWMSS subsystem that can be used for this purpose. See section 15.2 of the AM335x TRM Rev. P for details.

Hi Biser-san,

Thank you for your reply.

The ePWMs cannot be used in the customer design because the pins conflict between the ePWMs and other peripherals.

Best regards,

Daisuke
