Port 2 Mask Value.
Selects P2 pins to be compared to the corresponding bits in P2MAT.
0: P2.n pin logic value is ignored and cannot cause a Port Mismatch event.
1: P2.n pin logic value is compared to P2MAT.n.
Port 2 Match Value.
Match comparison value used on Port 2 for bits in P2MAT which are set to 1.
