Bits7–0: Output Configuration Bits for P0.7–P0.0 (respectively): ignored if corresponding bit in regis- ter P0MDIN is logic 0.

0: Corresponding P0.n Output is open-drain.

1: Corresponding P0.n Output is push-pull.

(Note: When SDA and SCL appear on any of the Port I/O, each are open-drain regardless of the value of P0MDOUT).

Bits7–0: P0SKIP[7:0]: Port0 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 P0.n pin is not skipped by the Crossbar.

1: Corresponding P0.n pin is skipped by the Crossbar.
