Descripción

/CS1B

This is 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.

VSS

Power supply

Ground

VOUT

DC/DC voltage converter. Connect a capacitor between this terminal and vss or VDD

CAP3P

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.

CAP1N

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal.

CAP1P

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.

CAP2P

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal.

CAP2N

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal.

V4~V0

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.

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

No connection.
