SFR Definition 13.13. P2MDOUT: Port2 Output Mode

SFR Definition 13.14. P2SKIP: Port2 Skip

Bits7–0: Output Configuration Bits for P2.7–P2.0 (respectively): ignored if corresponding bit in regis-

ter P2MDIN is logic 0.

0: Corresponding P2.n Output is open-drain.

1: Corresponding P2.n Output is push-pull.

Note:

Only P2.0–P2.5 are associated with Port pins on the C8051F316/7 devices.

Bits7–0: 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.

Note:

Only P2.0–P2.3 are associated with the Crossbar.
