    Interrupt for buried component pin


      For my design i'm using a SCB SPI slave component and need to generate a interrupt from slave select. This pin is hidden from the top level schematic so i cant simply place a ISR component on this I/O line. 

      I need the steps for enabling the interrupt at the GPIO pin and all other steps up to the ISR service function. I have so far determined these steps but dont have the complete solution: 

      Create ISR prototype 
      Create function 
      Link function to interrupt vector??? I believe port 5 is connected to IRQ5 

      Enable interrupt vector??? 

      Enable Pin interrupt
