IN1PL: /INT1 Polarity
0: /INT1 input is active low.
1: /INT1 input is active high.
IN1SL2-0: /INT1 Port Pin Selection Bits
These bits select which Port pin is assigned to /INT1. Note that this pin assignment is independent 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
P0SKIP).
IN0PL: /INT0 Polarity
0: /INT0 interrupt is active low.
1: /INT0 interrupt is active high.
INT0SL2-0: /INT0 Port Pin Selection Bits
These bits select which Port pin is assigned to /INT0. Note that this pin assignment is independent of
the Crossbar. /INT0 will monitor the assigned Port pin without disturbing the peripheral that has been
