Hi,

I am using the GPIO pins of the DM648 DSP. I am able to write and clear the GPIO SET_DATA and
CLR_DATA registers of the GPIO peripheral and toggle the GPIO pins. 
But I want to receive the GPIO interrupt to the CPU. I am able to understand that the  GPIO
interrupt registers can be configured for both rising and falling edge interrupts, but can
anyone help me on how to configure the HWI module of the DSP/BIOS tcf file and receive the GPIO
interrupt using an Interrupt service routine.

Thanks in advance,
Karthik.
