Hi,

I am using MIMXRT1052. I generated pwm output signals by either flexPwm or by Quarter Timer. I want to use the rising or falling edge of this pwm signal to trigger DMA that reads data from the existing source then writes the data to gpio output pin. I read the MIMXRT1050 reference manual but I could not find the right registers to do this. Please help.

 

 

Thank you.
