Note 1: Even when open-drain mode is selected, the protective diode remains connected. Therefore, do not apply voltages ex-
Note 2: Read-Modify-Write (RMW) operation executes at open-drain mode is selected, read out the output latch states.
Note 3: For PMD circuit output, set the P3DR output latch to 1.
Note 4: When using P3 port as an input/output port, disable the EMG1 circuit.
