13.2.2.19 External Interrupt Configuration Register (INTCONFIG)

This register configures the individual external interrupts to be either edge-sensitive or
level-sensitive, and either active HIGH or active LOW. Following reset, all bits are 0 and
configure the external interrupts to be active LOW, level sensitive.
The corresponding edge-trigger interrupt should be cleared before enabling the edge-
trigger interrupt to avoid a false interrupt.
