Emios(PWM-GPT)

To provide the period to Emios_pwm, I use the Emios_mcl driver. In addition, I use Emios_gpt to trigger the BCTU.

My issue is that when the emios_gpt is activated. emios_pwm outputs a default value ??, What may be the cause of this ?

I am using S32K344 evolution board.

I can't see how EMIOS triggers Bctu when used as Gpt, but I guess it is based on some flags or internal outputs

"To request an ADC conversion through the BCTU, a timer module such as eMIOS asserts its output signal, which is connected to a BCTU trigger input."

I hope you can read the data sheet later or write some test code yourself. This is the test routine I made for Gpt->Bctu->Adc. You can refer to it.
