Thank you so much for your interest in our products and for using our community.
I am sorry to inform you that so far we do not have that specific example code with the PWMA/eFlexPWM module.
The closest I've found to what you're looking for, which you could use as a reference, are the application notes AN5121 and AN4598, as well as the SDK example evkbimxrt1050_qtmr_inputcapture_outputpwm_dma. Although I must clarify that they are for other devices.
Please excuse any inconvenience this may cause you.
Have a nice day!
