IN0SL INT0 Port Pin Selection Bits.
These bits select which Port pin is assigned to INT0. This pin assignment is independent
of the Crossbar; INT0 will monitor the assigned Port pin without disturbing the peripheral
that has been assigned the Port pin via the Crossbar. The Crossbar will not assign the
Port pin to a peripheral if it is configured to skip the selected pin.
