Part Number: TMS320F280025

I am using C280025 with 80 pin.

I am trying to use GPIO46 as trip zone input, but it can not trigger the TZ protect.

While other pins can succeful trigger it (I have try GPIO29\GPIO16|GPIO33).

Is there any problem with the last GPIO of the chip.

And I am sure the code is right.

Hi Jerry,

Can you verify that you're able to get a signal off of GPIO46 at all, such as a typical logic high output? If so, can you attach an image of the GPIO configuration code for GPIO46?

There does not appear to be any known disconnect issue with GPIO46.

Regards,

Jason Osborn
