i.MX.RT1052 - Is it possible to create a 32bit PWM module using 2 quad timers?

Hi,

Is it possible to generate a 32-bit PWM output using 2 quad timers?

in this post:-

https://community.nxp.com/t5/Digital-Signal-Controllers/32-bit-compare-with-the-Quad-Timer/m-p/820198

xiangjun_rong mentioned that:-

"when you use Cascaded counter mode for T3, and T2 output is the tick for T3, the T3:T2 is NOT a standard 32bits single Timer"

My questions is:-

a) How to combine 2 quad timers to form a 32-bit PWM module if cascading 2 quad timers is not the way to do it?

Thank you.

Best Regards,

Cindy

Hi，
Thanks for your reply.
1）Is it possible to generate a 32-bit PWM output using 2 quad timers?
-- No, the Quad Timer (TMR) doesn't support the feature.
Have a great day,
