The default comparison value is configured in the
DEFVAL register. If enabled (via GPINTEN and
INTCON) to compare against the DEFVAL register, an
opposite value on the associated pin will cause an
interrupt to occur.

DEFAULT COMPARE REGISTER
FOR INTERRUPT-ON-CHANGE
DEF7:DEF0: These bits set the compare value for pins configured for interrupt-on-change from
defaults <7:0>. Refer to INTCON.
If the associated pin level is the opposite from the register bit, an interrupt occurs.
Refer to INTCON and GPINTEN.
