Hi I am using FMS320F280025, i would like to know that what way to check pin is configured as EPWM or GPIO?

Hi Hung,

Thanks for your question. You can view the GPyGMUX and GPyMUX registers to see the mux configuration of a GPIO pin.

Hi Hung,

1. Can you view the TRM to see "GPAGMUX" or "GPAMUX"? You can also see these registers in the "Registers" view of CCS.

2. You can use HWREGH (from hw_types.h file) command in driverlib to do a direct read of a register.

Regards,

Vince
