    P/S

    This pin configures the interface to be parallel mode or serial mode. P/S = “H”: Parallel data input/output.

    P/S = “L”: Serial data input.

    C86

    This is the MPU interface selection pin. C86 = “H”: 6800 Series MPU interface.

    C86 = “L”: 8080 Series MPU interface.

    V5~V1

    This is a multi-level power supply for the liquid crystal drive. The voltage Supply applied is determined by the liquid crystal cell, and is changed through the use of a resistive voltage divided or through changing the impedance using an op. amp. Voltage levels are determined based on Vss, and must maintain the relative magnitudes shown below.

    E

    • When connected to 8080 series MPU, this pin is treated as the “/RD” signal of the 8080 MPU and is LOW-active.

    The data bus is in an output status when this signal is “L”.

    • When connected to 6800 series MPU, this pin is treated as the “E” signal of the 6800 MPU and is HIGH-active.

    This is the enable clock input terminal of the 6800 Series MPU.

    A0

    This is connect to the least significant bit of the normal MPU address bus, and it determines whether the data bits are data or command.

    A0 = “H”:Indicates that D0 to D7 are display data. A0 = “L”: Indicates that D0 to D7 are control data
