IN1PL: /INT1 Polarity
0: /INT1 input is active low.
1: /INT1 input is active high.
These bits select which Port pin is assigned to /INT1. Note that this pin assignment is inde-
pendent of the Crossbar; /INT1 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 (accomplished by
setting to ‘1’ the corresponding bit in register XBR0).
IN0PL: /INT0 Polarity
0: /INT0 interrupt is active low.
1: /INT0 interrupt is active high.
These bits select which Port pin is assigned to /INT0. Note that this pin assignment is inde-
pendent 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 (accomplished by
setting to ‘1’ the corresponding bit in register XBR0).
