Chip enable terminal. It is active when /CS=”L”.
When /RES is set to “L”, the register settings are initialized (cleared).
The reset operation is performed by the /RES signal level.
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.
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
This is the enable clock input terminal of the 6800 Series MPU and is
HIGH-active.
This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit
standard MPU data bus.

DC/DC voltage converter. Connect a capacitor between this terminal and
VSS or VDD terminal.
DC/DC voltage converter. Connect a capacitor between this terminal and the
C1- terminal.
DC/DC voltage converter. Connect a capacitor between this terminal and the
C1+ terminal.
DC/DC voltage converter. Connect a capacitor between this terminal and the

DC/DC voltage converter. Connect a capacitor between this terminal and the
C2- terminal.
DC/DC voltage converter. Connect a capacitor between this terminal and the
C2+ terminal.
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.
V0≥V1≥V2≥V3≥V4≥VSS
This is the MPU interface switch terminal
C86=“H” : 6800 series MPU interface
C86=“L” : 8080 MPU interface
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.
The following applies depending on the P/S status:
P/S Data/Command Data Read/Write 4-lineSPI Clock
“H” A0 D0 to D7 /RD, /WR x
“L” A0 SI (D7) Write only SCL (D6)
When P/S = “L”, D0 to D5 must be fixed to “H”.
/RD (E) and /WR (R/W) are fixed to either “H” or “L”.
The serial access mode does NOT support read operation.

16. LCD MODULES HANDLING PRECAUTIONS
The display panel is made of glass. Do not subject it to a mechanical shock by dropping it from a high place, etc.
If the display panel is damaged and the liquid crystal substance inside it leaks out, d o not get any in your m outh. If the
substance come into contact with your skin or clothes promptly wash it off using soap and water.
Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary.
The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarize
carefully.
To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment.
-Be sure to ground the body when handling the LCD module.
-Tools required for assembly, such as soldering irons, must be properly grounded.
-To reduce the amount of static electricity generated, do not conduct assembly and other work under dry conditions.
-The LCD module is coated with a film to protect the display surface. Exercise care when peeling off this protective
film since static electricity may be generated.
Storage precautions
When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps. Keep the
modules in bags designed to prevent static electricity charging under low temperature / normal humidity conditions
(avoid high temperature / high humidity and low temperatures below -20°C). Whenever possible, the LCD modules
should be stored in the same conditions in which they were shipped from our company.
17. OTHERS
Liquid crystals solidify at low temperature (below the storage temperature range) leading to defective orientation of
liquid crystal or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is
subjected to a strong shock at a low temperature.
If the LCD modules have been operating for a long time showing the same display patterns may remain on the screen
as ghost images and a slight contrast irregularity may also appear. Abnormal operating status can be resumed to be
normal condition by suspending use for some time. It should be noted that this phenomena does not adversely affect
performance reliability.
To minimize the performance degradation of the LCD modules resulting from caused by static electricity, etc.
exercise care to avoid holding the following sections when handling the modules:
- Exposed area of the printed circuit board
- Terminal electrode sections
