Only P1.0–P1.5 are associated with Port pins on the C8051F316/7 devices.
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 (VREF input, external oscil-
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.
Only P1.0–P1.5 are associated with Port pins on the C8051F316/7 devices. Hence, in C8051F316/7
devices, user code writing to this SFR should always set P1SKIP[7:6] = 11b so that those two pins are
skipped by the crossbar decoder.
