P2SKIP[7:0]: Port2 Crossbar Skip Enable Bits.

These bits select Port pins to be skipped by the Crossbar Decoder. Port pins used as ana-

log inputs (for ADC or Comparator) or used as special functions (VREF input, external oscil-

lator circuit, CNVSTR input) should be skipped by the Crossbar.

0: Corresponding P2.n pin is not skipped by the Crossbar.

1: Corresponding P2.n pin is skipped by the Crossbar.
