Output Configuration Bits for P3.4–P3.0 (respectively): ignored if corresponding bit in regis-
ter P3MDIN is logic 0.
0: Corresponding P3.n Output is open-drain.
1: Corresponding P3.n Output is push-pull.
Note:
Only P3.0–P3.4 are associated with Port pins on C8051F310/2/4 devices; Only P3.0 is associated with a
Port pin on C8051F311/3/5/6/7 devices.
