TMS320F2809: The application issues of chips

Tonyx.wu

Part Number: TMS320F2809

Tool/software:

Can all io ports of the F2809 model generate an interrupt function

It is said online that only pins 0 to 31 have the interrupt function

We input the gpio34 key in our circuit diagram

Hi,

I am unable to grasp any information from the screenshot you shared in regards to gpio configuration for gpio34.

However, it is as you mentioned, only Port A (GPIO[0:31]) has the configuration registers for XINT[1:2] and XNMI.

This means that GPIO34 will be unable to post an interrupt to the PIE.

Best Regards,
