SFR Definition 13.11. P1MDOUT: Port1 Output Mode
SFR Definition 13.12. P1SKIP: Port1 Skip
Note: When SDA and SCL appear on any of the Port I/O, each are open-drain regardless of the value of P0MDOUT.

ter P1MDIN is logic 0.
0: Corresponding P1.n Output is open-drain.
1: Corresponding P1.n Output is push-pull.
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 (V
lator 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.
