4. COMMUNICATION WITH MPU
4.1 RAM Map
The Display RAM is built in the module, and display data (text, graphic and CG data) is
written to this display RAM. The built-in controller T6963C automatically reads the display
RAM and sends the appropriate data to LCD drivers. The “Control Word Set” command
(text home set, text area set, etc.) defines the RAM area which is read by the controller
T6963C making the RAM map programmable by the user. If more than 1 screen can be
stored in the RAM. Vertical scrolling and paging is easily performed by resetting text home
and/or graphic home address.
The 32K bytes built-in RAM is located at address 0000H ~ 7FFFH, and the following is an
example of RAM mapping.

4.2 Status Read
Status of the T6963C should be checked between all command and data in order to
complete a communication cycle with the MPU. The status can be read from 8 bits data
lines (D0 to D7) by setting C/D=“H”, /RD=“L”, /WR=“H” and /CE=“L”.
The T6963C status word format is as follows:

FUNCTION
5.1.1 Set Cursor Pointer
The position of the cursor is specified by X ADRS AND Y ADRS. The cursor position can
only be moved by this command. Data read/write from the MPU never changes the cursor
pointer. X ADRS and Y ADRS are specified as follows.
X ADRS: 00H to 4FH, Horizontal cursor position counted by “character”, 6 or 8 dots width.
Y ADRS: 00H to 1FH, Vertical cursor position counted by “character”, 8 dots height.
Note: Please note that the cursor position should be within actual display area.
5.1.2 Set Offset Register
The Set Offset Register command is used to determine the character generator RAM area.
The upper 5 bits in start address of CG area is set as the lower 5 bits of D1, and the upper
3 bits of D1 are neglected. D2 should be 00H. Refer to section 7 “Character Generator” for
details of the CG RAM.
5.1.3 Set Address Pointer
The Set Address Pointer command is used to indicate the start address for writing/reading
data to/from the built-in RAM.

The home address of display RAM and column size are defined by this command.
5.2.1 Set Text Home Address (TH)
This command defines the starting address of display RAM for text display. The data in
the text home address (TH) is displayed at the home position of display (left end character
on 1st row.)
5.2.2 Set Text Area (TA)
This command defines the number of columns by D1. Text area can be defined
independently from the number of characters fixed by hardware setting of controller LSI.
The text area is usually defined as the actual number of characters on LCD display, so
addressing can be continuous in the text area.

5.2.3 Set Graphic Home Address (GH)
This command defines the starting address of display RAM for the graphic display. The
data in the Graphic home address (GH) is displayed at the home position of display (left
end 8 bits in 1st line). When using the attribute function, the graphic home address
indicates the starting address of distribute RAM area.
5.2.4 Graphic Address Set (GA)
This command defines the number of columns by D1. The graphic area can be defined
independently from the number of characters fixed by hardware setting of controller LSI. If
the graphic area is defined as the actual number of columns on the LCD display, the
address in graphic area can be continuous and the RAM area can be used without
ineffective areas. Note that the Graphic area will be different for depending on character
font settings even if horizontal dot number is the same.

Mode set command selects character generator (CG ROM Mode/CG RAM Mode), and
combination of text/graphic display. The display mode does not change until the next
command is sent. The logical OR, EXOR, AND of text or graphic display can be displayed.
CG ROM mode: Built-in 128 character CG ROM (code: 00H - 7FH) and built-in CG RAM
for 128 characters can be used (code: 80H - FFH).
CG RAM mode: Built-in CG RAM for 256 characters (code: 00H - FFH) can be used.
When CG ROM Mode is selected, character code 00H - 7FH is selected from built-in CG
ROM and character code 80H – FFH is automatically selected from CG RAM.

Attribute function
Attribute operations are “Reverse display”, “Character blink” and “Inhibit” in text display
mode. The attribute data is written in the graphic area defined by Set Control Word
command (Graphic home address set and Graphic area set). Only text display is possible
in Attribute Function mode, since the attribute data is stored in the graphic RAM area,
graphic display is automatically disabled. However, the Display Mode command must be
used to turn both Text and Graphic on in order for the Attribute function to be available.
The attribute data of the 1st character in “Text area” is written at the 1st byte in “graphic
area”, and attribute data of nth character is written at the nth byte in “Graphic area”.
The attribute function is defined as follows.

This command is convenient to send full screen data, or receive full screen data from
built-in RAM. After setting auto mode, a Data Write (or Read) command is not need
between each data. Data Auto Write (or Read) command should follow the Address
Pointer Set command. After this command, the address pointer is automatically
incremented by +1 after each data. After sending (or receiving) all data, Auto Mode Reset
command is necessary to return normal operation because all data is regarded “display
data” and no command can be accepted in the auto mode.
(Note) Status check for Auto mode (STA2 or STA3) should be checked between each
data. Auto Reset should be performed after checking STA3=1(or STA2=1).

The character generator RAM is the built-in RAM which can be used as character
generator after writing character pattern by program. Part of built-in RAM can be used as
“User CG RAM” for 256 characters by selecting “CG RAM Mode”, or for 128 characters by
selecting “CG ROM Mode”.
The upper 5 bits (NNNNN) in start address of User CG RAM is defined by “Registers
Setting” command (Set Offset Register), and following 2048 bytes are defined as “User
CG RAM” area when CG RAM Mode is selected; 1024 bytes (address:
NNNNN10000000000 ~NNNNN11111111111) is defined as “User CG RAM” area when
CG ROM Mode is selected.

Character pattern can be displayed by sending CG code with “Data Write” command. But
“Set Display Mode” for text display should be selected before using CG. In case that “CG
ROM Mode” is selected, character pattern is selected from built-in CG ROM when MSB=0
(00H - 7FH), and from User CG RAM when MSB=1 (80H-FFH). In case that “CG RM
Mode” is selected, all character patterns are selected from User CG RAM (00H-FFH).
(Note) It must be careful so that User CG RAM area should not be rewritten by display
data, etc.

11. PRECAUTIONS FOR USE OF LCD MODULE
11.1 Handing Precautions
1) The display panel is made of glass. Do not subject it to a mechanical shock by
dropping it from a high place, etc.
2) If the display panel is damaged and the liquid crystal substance inside it leaks out,
be sure not to get any in your mouth. If the substance comes into contact with your
skin or clothes, promptly wash it off using soap and water.
3) Do not apply excessive force on the surface of display or the adjoining areas of
LCD module since this may cause the color tone to vary.
4) The polarizer covering the display surface of the LCD module is soft and easily
scratched. Handle this polarizer carefully.
5) If the display surface of LCD module becomes contaminated, blow on the
surface and gently wipe it with a soft dry cloth. If it is heavily contaminated, moisten
cloth with one of the following solvents.
· Isopropyl alcohol
· Ethyl alcohol
Solvents other than those mentioned above may damage the polarizer.
Especially, do not use the following:
· Water
·
Ketone
· Aromatic Solvents
6) When mounting the LCD module make sure that it is free of twisting, warping, and
distortion. Distortion has great influence upon display quality. Also keep the
stiffness enough regarding the outer case.
7) Be sure to avoid any solvent such as flux for soldering never stick to Heat-Seal.
Such solvent on Heat-Seal may cause connection problem of heat-Seal and TAB.
8) Do not forcibly pull or bend the TAB I/O terminals.
9) Do not attempt to disassemble or process the LCD module.
10) NC terminal should be open. Do not connect anything.
11) If the logic circuit power is off, do not apply the input signals.
12) 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.
11.2 Storage Precautions
LG240641-SFLYH6V
- 31 -
1) When storing the LCD module, avoid exposure to direct sunlight or to the light of
fluorescent lamps and high temperature/high humidity. Whenever possible, the
LCD module should be stored in the same conditions in which they were shipped
from our company.
2) Exercise care to minimize corrosion of the electrodes. Corrosion of the electrodes is
accelerated by water droplets or a current flow in a high humidity environment.
11.3 Design Precautions
1) The absolute maximum ratings represent the rated value beyond which LCD module
can not exceed. When the LCD modules are used in excess of this rated value, their
operating characteristics may be adversely affected.
2) To prevent the occurrence of erroneous operation caused by noise, attention must
be paid to satisfy VIL, VIH specification values, including taking the precaution of
using signal cables that are short.
3) The liquid crystal display exhibits temperature dependency characteristics. Since
recognition of the display becomes difficult when the LCD is used outside its
designated operating temperature range, be sure to use the LCD within this range.
Also, keep in mind that the LCD driving voltage levels necessary for clear displays
will vary according to temperature.
4) Sufficiently notice the mutual noise interference occurred by peripheral devices.
5) To cope with EMI, take measures basically on outputting side.
6) If DC is impressed on the liquid crystal display panel, display definition is rapidly
deteriorated by the electrochemical reaction that occurs inside the liquid crystal
display panel. To eliminate the opportunity of DC impressing, be sure to maintain
the AC characteristics of the input signals sent to the LCD Module.
11.4 Others
1) Liquid crystals solidify under low temperatures (below the storage temperature
range) leading to defective orientation or the generation of air bubbles (black or
white).
Air bubbles may also be generated if the LCD module is subjected to a strong
shock at a low temperature.
2) If the LCD modules have been operating for a long time showing the same display
patterns, the display patterns may remain on the screen as ghost images and a
slight contrast irregularity may also appear. A normal operating status can be
regained by suspending use for some time. It should be noted that this
phenomenon does not adversely affect performance reliability.
3) To minimize the performance degradation of the LCD modules resulting from
destruction caused by static electricity, etc., exercise care to avoid touching the
following sections when handling the module:
· Terminal electrode sections.
· Part of pattern wiring on TAB, etc.
