Port 1 Mask Value.
Selects P3 pins to be compared to the corresponding bits in P3MAT.
0: P3.n pin logic value is ignored and cannot cause a Port Mismatch event.
1: P3.n pin logic value is compared to P3MAT.n.
Port 3 Match Value.
Match comparison value used on Port 3 for bits in P3MAT which are set to 1.
0: P3.n pin logic value is compared with logic LOW.
1: P3.n pin logic value is compared with logic HIGH.
