Doubt in GPIO Interrupt

Started by karthikeyan B May 7, 2008

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,
