Bits7-0: Output Configuration Bits for P1.7-P1.0 (respectively): ignored if corresponding bit in register
P1MDIN is logic 0.

Figure 14.14. P1SKIP: Port1 Skip Register
Bits7-0: P1SKIP[7:0]: Port1 Crossbar Skip Enable Bits.
These bits select Port pins to be skipped by the Crossbar Decoder. Port pins used as analog inputs (for
ADC or Comparator) or used as special functions (VREF input, external oscillator circuit, CNVSTR
input) 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.
