Hello NXP team.
I would like to know how can I start two PWM signals at the same time ?
I'm writing code for S32K344 and S32K341 MCU and at the moment I'm using S32K3X4EVB-Q172 devBoard for development.
I have to create two PWM signals with frequency 10KHz and fixed phase difference 60 degrees and duty cycle will change from the user.
PWM_A 10 KHZ 50%duty (variable duty)
PWM_B 10 KHZ 50%duty (variable duty) + 60 degrees phase difference from PWM_A
And I need 1 more PWM signal @400KHz that will be synced with PWM_A. I need those two signals to start at the same time.
I have studied eMIOS but I can't remember of a way to sync signals. I will go and study again the reference manual in case I've missed something out.
Kind regards,
kyf

Synchronizing of two eMIOS instance you may see described here:

But what you are describing are just multichannel PWM, I don't see any need of synchronization as both channels will be derived from same counter bus.
