说明

/CS1

The chip select signal

/RES

When RES is set to “L”, the setting are initialized.

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.

/WR(R/W)

• When connected to 8080 series MPU, this pin is treated as the “/WR” signal of the 8080 MPU and is LOW-active.
The signals on the data bus are latched at the rising edge of the /WR signal.
• When connected to 6800 series MPU, this pin is treated as the “R/W” signal of the 6800 MPU and decides the access type :
When R/W = “H”: Read.
When R/W = “L”: Write.

/RD(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.

Power
Supply

This is the internal-output VREG power supply for the LCD power supply voltage
regulator.

Power
Supply

This is a multi-level power supply for the liquid crystal drive.

Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider.
IRS = “L” : the V0 voltage regulator internal resistors are not used.
IRS = “H” : the V0 voltage regulator internal resistors are used.

C86

This is the MPU interface selection pin.
C86 = “H”: 6800 Series MPU interface.
C86 = “L”: 8080 Series MPU interface

P/S

This is the parallel data input/serial data input switch terminal.
P/S = “H”: Parallel data input.
P/S = “L”: Serial data input.
The following applies depending on the P/S status:

P/S	Data/Command	Data	Read/Write	Serial Clock
"H"	A0	D0 to D7	/RD,/WR	X
"L"	A0	SI(D7)	Write only	SCL(D6)

When P/S = “L”, D0 to D5 fixed “H”.
/RD (E) and /WR (R/W) are fixed to either “H” or “L”.
With serial data input, It is impossible read data from RAM

/HPM

This is the power control terminal for the power supply circuit for liquid crystal drive.
/HPM = “H”: Normal mode
/HPM = “L”: High power mode

IRS

This terminal selects the resistors for the V0 voltage level adjustment.
IRS = “H”: Use the internal resistors
IRS = “L”: Do not use the internal resistors. The V0 voltage level is
regulated by an external resistive voltage divider attached to the VR terminal
