EXTERNAL INTERRUPT pins are used to request interrupt service. The XINT7:0
pins can be configured in three modes:
Dedicated Mode: Each pin is assigned a dedicated interrupt level. Dedicated inputs
can be programmed to be level (low) or edge (falling) sensitive.
Expanded Mode: All eight pins act as a vectored interrupt source. The interrupt pins
are level sensitive in this mode.
Mixed Mode: The XINT7:5 pins act as dedicated sources and the XINT4:0 pins act
as the five most significant bits of a vectored source. The least significant bits of the
vectored source are set to 010
Unused external interrupt pins should be connected to V
NON-MASKABLE INTERRUPT causes a non-maskable interrupt event to occur.
NMI is the highest priority interrupt source and is falling edge-triggered. If NMI is
unused, it should be connected to V
