It is possible to mask each individual interrupt (except Watchdog time-out). The interrupts in the Interrupt Pending Register

are cleared automatically when the interrupt is acknowledged.

By programming the Interrupt Shape Register, it is possible to define the external interrupts to be either active low or active

high and to define the external interrupts to be either edge or level sensitive.
