Interrupt Edge Select Register  
The Interrupt Edge Select (IRQES) register (Table 46) determines whether an interrupt is  
generated for the rising edge or falling edge on the selected GPIO Port A or Port D input  
pin.

IESx—Interrupt Edge Select x  
0 = An interrupt request is generated on the falling edge of the PAx input or PDx.  
1 = An interrupt request is generated on the rising edge of the PAx input PDx.  
where x indicates the specific GPIO Port pin number (0 through 7).  
Shared Interrupt Select Register  
The Shared Interrupt Select (IRQSS) register (Table 47) determines the source of the  
PADxS interrupts. The Shared Interrupt Select register selects between Port A and alter-  
nate sources for the individual interrupts.
