7:0 P1SKIP[7:0] Port 1 Crossbar Skip Enable Bits.
Function
These bits select Port 1 pins to be skipped by the Crossbar Decoder. Port pins used
for analog, special functions or GPIO should be skipped by the Crossbar.
0: Corresponding P1.n pin is not skipped by the Crossbar.
1: Corresponding P1.n pin is skipped by the Crossbar.
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. P1.3 and P1.4 should always be skipped in the crossbar.
