Hello @Steven_Tai 

I suggest you referring SDK demo code pin interrupt. I believe it will help you.

how to use the GPIO00 interrupt slave mcu directly without pinmux? I was failed with GPIO00_Interrupt to slave mcu.

If pin interrupt is needed, we must configure PINT_SEL registers in the INPUTMUX module to make sure the pin served as PINT function.
