UNUSED. Read = 000b; Write = don’t care.
Input Configuration Bits for P3.4-P3.0 (respectively).
Port pins configured as analog inputs have their weak pullup, digital driver, and digital
receiver disabled.
0: Corresponding P3.n pin is configured as an analog input.
1: Corresponding P3.n pin is not configured as an analog input.
Note: Only P3.0-P3.4 are associated with Port pins on C8051F10/2/4 devices; Only P3.0 is
associated with a Port pin on C8051F311/3/5 devices.
UNUSED. Read = 000b; Write - don’t care.
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 C8051F10/2/4 devices; Only P3.0 is
associated with a Port pin on C8051F311/3/5 devices.
