Write - Output appears on I/O pins.
0: Logic Low Output.
1: Logic High Output (high impedance if corresponding P3MDOUT.n bit = 0).
Read - Always reads ‘1’ if selected as analog input in register P3MDIN. Directly reads Port
pin when configured as digital input.
0: P3.n pin is logic low.
1: P3.n pin is logic high.
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.
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.
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.
