These bits control the value that unmasked P0 Port pins are compared against. A Port
Match event is generated if (P0 & P0MASK) does not equal (P0MAT & P0MASK).
These bits select which Port pins will be compared to the value stored in P0MAT.
0: Corresponding P0.n pin is ignored and cannot cause a Port Match event.
1: Corresponding P0.n pin is compared to the corresponding bit in P0MAT.
Port pins configured to High-Impedance Overdrive Mode do not require additional overdrive
current, although selecting this mode results in a slight increase in supply current. Port pins
configured to Normal Overdrive Mode require approximately 150 µA of input overdrive cur-
rent when the voltage at the pin reaches V
0: Corresponding P0.n pin is configured to Normal Overdrive Mode.
1: Corresponding P0.n pin is configured to High-Impedance Overdrive Mode.
