9.3.2.14 External Interrupt Clear Register

IntClear is the External Interrupt Clear Register. The active bits used in this register are
Write Only.
This register individually clears active external interrupts. This register can only clear edge-
triggered interrupts. Writing a one to a bit clears the corresponding active edge-triggered
interrupt. Writing to undefined bits has no effect on the RCPC.
