MPC5746B PWM with Master Bus Problem

[Ehsaaan]

Hello 

I am working on the MPC5748B-C-G Sample from NXP. I already ran the PWM module without any problem. but now I am trying PWM EMIOS1 Channel 19 Y and running a master bus channel 16 for it. but there is no output at the pin. what is the problem?
Kindly please find the attachments.

Hello @Ehsaaan ,

Could you please check the reference clock, cause I see that Emios should use FS80 clock instead.

Best regards,

I set the reference clock on FS80 and 80 MHz, but still not working. 
Are the settings of Master Bus ok? No need to set other modules like GPT? Or changes in interrupt vectors or initialization? it doesn't need any API to run the master bus ch16?

Hello @Ehsaaan ,

Please enable the global prescaler for EMIOS1 in the MCU configuration. Then we can see the output signal of EMIOS1
