9.INSTRUCTION DESCRIPTION
Outline
To overcome the speed difference between the internal clock of KS0070B and the MPU clock, KS0070B performs
internal operations by storing control information to IR or DR. The internal operation is determined according to the
signal from MPU, composed of read/write and data bus (refer to table 5.)
Instruction can be divided largely into four kinds:
(1) KS0070B function set instructions (set display methods, set data length, etc.)
(2) Address set instructions to internal RAM.
(3) Data transfer instructions with internal RAM.
(4) Others.
The address of the internal RAM is automatically increased or decreased by 1.
*NOTE: During internal operation, busy flag (DB7) is read”1”. Busy flag check must be preceded by the next
instruction.
When you make an MPU program with checking the busy flag (DB7), it must be necessary 1/2 fosc for executing the
next instruction by falling E signal after the busy flag (DB7) goes to “0”.

Clear all the display data by writing “20H”(space code) to all DDRAM address, and set the DDRAM addresses to
“00H” in the AC (address counter). Return cursor to original status, namely, bring the cursor to the left edge on first

Set the moving direction of cursor and display.
I/D: increment/decrement of DDRAM address is increased by 1.
When I/D=”1”, cursor/blink moves to right and DDRAM address is increased by 1.
When I/D=”0”, cursor/blink moves to left and DDRAM address is increased by 1.
CGRAM operates the same as DDRAM, when reading from or writing to CGRAM.
SH: shift of entire display
When DDRAM is in read (CGRAM read/write) operation or SH=”0”, shift of entire display is not performed.
If SH=”1” and in DDRAM write operation, shift of entire display is performed according to I/D value (I/D=”1”:
shift left, I/D=”0”: shift right).

Without writing or reading the display data, shift right/left cursor position or display.
This instruction is used to correct or search display data. (refer to table 40
During 2-line mode display, cursor moves to the 2nd line after the 40st digit of the 1st line.
Note tat display shift is performed simultaneously in all the lines.
When displayed data is shifted repeatedly, each line shifts individually.
When display shift is performed, the contents of the address counter are not changed.

Write binary 8-bit data to DDRAM / CGRAM
The selection of RAM from DDRAM, and CGRAM, is set by the previous address set instruction: DDRAM address
set, and CGRAM address set. RAM set instruction can also determine the AC direction to RAM.
After write operation, the address is automatically increased/decreased by 1, according to the entry mode.

Read binary 8-bit data from DDRAM/CGRAM.
The selection of RAM is set by the previous address set instruction. If the address set instruction of RAM is not
performed before this instruction, the data that is read first is invalid, because the direction of AC is not determined.
If you read RAM data several times without RAM address set instruction before read operation, you can get correct
RAM data. In the case of DDRAM read operation, cursor shift instruction plays the same role as DDRAM address
set instruction; it also transfers RAM data to the output data register.
After read operation the address counter is automatically increased/decreased by 1 according to the entry mode. After
CGRAM read operation, display shift may not be executed correctly.
In the case of RAM write operation, after this AC is increased/decreased by 1 like read operation. At his time, AC
indicates the next address position, but your can read only the previous data by the read instruction.

1) Interface with 8-bit MPU
When interfacing data length are 8-bit, transfer is performed all at once through 8-ports, from DB0 to DB7.

2) Interface with 4-bit MPU
When interfacing data length are 4-bit, only 4 ports, from DB4 to DB7, are used as data bus.
At first, higher 4-bit (in case of 8-bit bus mode, the contents of DB4 to DB7) are transferred, and then the lower 4-bit
(in case of 8-bit bus mode, the contents of DB0 to DB3) are transferred. So transfer is performed in two parts. Busy
flag outputs”1”after the second transfer are ended.

16. LCD Modules Handling Precautions
n
The display panel is made of glass. Do not subject it to a mechanical shock by dropping it from a
high place, etc.
n
If the display panel is damaged and the liquid crystal substance inside it leaks out, do not get any
in your mouth. If the substance come into contact with your skin or clothes promptly wash it off
using soap and water.
n
Do not apply excessive force to the display surface or the adjoining areas since this may cause the
color tone to vary.
n
The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle
this polarize carefully.
n
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.
n
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 0°C).Whenever possible, the LCD modules should be stored in the same
conditions in which they were shipped from our company.
17. Others
n
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.
n
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.
n
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
