8.2.2
IEG
This pin selects the interrupt edge to be detected on the INT pin.
When this flag is 0, the interrupt is detected at the rising edge; when it is 1, the interrupt is detected at the falling
edge.
8.2.3
INTSEL
This flag selects whether pin 3 is used as the INT pin or P1B0 pin. When INTSEL is cleared to 0, pin 3 functions
as the P1B0 pin; when it is set to 1, the pin functions as the INT pin.
After reset, the P1B0 pin is selected.
