Figure 14.13. P1MDOUT: Port1 Output Mode Register

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

P1MDIN is logic 0.

0: Corresponding P1.n Output is open-drain.

1: Corresponding P1.n Output is push-pull.

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.
