The INTF register reflects the interrupt condition on the
port pins of any pin that is enabled for interrupts via the
GPINTEN register. A ‘set’ bit indicates that the
associated pin caused the interrupt.
This register is ‘read-only’. Writes to this register will be
ignored.

INTERRUPT FLAG REGISTER
INT7:INT0: These bits reflect the interrupt condition on the port. Will reflect the change only if interrupts
are enabled (GPINTEN) <7:0>.
1 = Pin caused interrupt.
0 = Interrupt not pending.
