P1MASK[7:0]
Port 1 Mask Value.
Function
Selects P1 pins to be compared to the corresponding bits in P1MAT.
0: P1.n pin logic value is ignored and cannot cause a Port Mismatch event.
1: P1.n pin logic value is compared to P1MAT.n.
Note:
P1.0, P1.1, P1.2, and P1.4 are internally connected to the EZRadioPRO peripheral. P1.3 is not externally or
internally connected.

P1MAT[7:0]
Port 1 Match Value.
Function
Match comparison value used on Port 1 for bits in P1MASK which are set to 1.
0: P1.n pin logic value is compared with logic LOW.
1: P1.n pin logic value is compared with logic HIGH.
Note:
P1.0, P1.1, P1.2, and P1.4 are internally connected to the EZRadioPRO peripheral. P1.3 is not externally or
internally connected.
