I am attempting to setup the port p interrupt on a MC9S12C32 process (NanoCore from technological arts) as shown below. I am trying to use the interrupt to read in a 1 Hz signal from a Real Time Clock therefore, I set Port P up as an input and enabled the interrupt inside the PIEP register (although just to write the declaration I should not even need to do this).
interrupt 56 void 1Hz_handler(void) // port P5
I keep getting an error stating that this is an invalid number. I have counted up in the vector table several times and I keep getting Vportp to be 56. Has anybody used the port p vectors?
