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 instruction 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" .
Contents
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 0 0 0 0 0 1
Clear all the display data by writing "20H" (space code) to all DRAM addresses, and set the DRAM addresses
to "00H" in the AC (address counter). Return cursor to original status, namely, bring the cursor to the left edge
on first line of the display . Make entry mode increment (I/D = "1" ) .
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
Return Home is the cursor return home instruction .
Set DRAM address to "00H" in the address counter. Return cursor to its original site and return display to its
original status, if shifted, Contents of DDRAM does not change .
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
Set the moving direction of cursor and display .
I/D : Increment/decrement of DDRAM address (cursor or blink )
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 ).

When D = "1" , entire display is turned on .
When D = "0" , display is turned off, but display data is remained in DDRAM .
C : Cursor ON/OFF control bit
When C = "1" , cursor is turned on.
When C = "0" , cursor is disappeared in current display, but I/D register remains its data .
B : Cursor Blink ON/OFF control bit
When B = "1" , cursor blink is on , that performs alternate between all the "1" data and display character at
the cursor position.
When B = "0" , blink is off.

This instruction is used to correct or search display data . (Refer to Table 4)
During 2-line mode display, cursor moves to the 2nd line after 40th digit of 1st line .
When displayed data is shifted repeatedly, each line shifted individually .
When displayed shift is performed, the contents of address counter are not changed .
Table 4 Shift patterns according to S/C and R/L bits
S/C R/L Operation
Shift cursor to the left, AC is decreased by 1
Shift cursor to the right, AC is decreased by 2
Shift all the display to the left, cursor moves according to the display
Shift all the display to the right, cursor moves according to the display

DL : Interface data length control bit
When DL = "1" , it means 8-bit bus mode with MPU.
When DL = "0" , it means 4-bit bus mode with MPU. So to speak, DL is a signal to select 8-bit or 4-bit bus mode .
When 4-bit bus mode, it needs to transfer 4-bit data in two parts .
N : Display line number control bit
When N = "1" , 2-Line display mode is set .
When N = "0" , 1-Line display mode is set .
F : Display font type control bit
When F = "0" , 5 X 7 dots format display mode .
When F = "1" , 5 X 10 dots format display mode .

0 0 1 AC6 AC5 AC4 AC3 AC2 AC1 AC0
Set DDRAM Address to AC .
This instruction makes DDRAM data available from MPU.
In 1-line display mode (N=0, NW=0), DDRAM address is from "00H" to "4FH".
In 2-line display mode (N=1, NW=0), DDRAM address in the 1st line is from "00H" to "27H",and DDRAM address in
the 2nd line is from "40H" to "67H".
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
This instruction shows whether KS0070B is in internal operation or not. If the resultant BF is High, the internal operaation is in progress and should wait until BF to become "Low", which by then the next instruction can be performed.
In this instruction value of address counter can also be read.
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
Write binary 8-bit data to DRAM/CRAM/SEAGRAM.
The selection of RAM from DRAM, CRAM or SEAGRAM, is set by the previous address set instruction: DDRAM
address set, CGRAM address set, SEGRAM address set, RAM set instruction can also determines the AC
direction to RAM.
After write operation, the address is automatically increased/decreased by 1, according to the entry mode.
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
Read binary 8-bit data to DDRAM/CRAM .
The selection of RAM is set by the previous address set instruction. If address set instruction of RAM is not
performed before this instruction, the data that read first is invalid, as the direction of AC is not determined. If the
RAM data is read several times without RAM address set instruction before read operation, the correct RAM data
from the second, but the first data would be incorrect, as there is not time to transfer RAM data. In case of DDRAM
read operation, cursor shift instruction plays the same role as DDRAM address set instruction: it also transfer RAM
data to output data register.
After read operation 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 case of RAM write operation, AC is increased/decreased by 1 like read operation after this. In this time, AC
indicates the next address position, but the previous data can only by read instruction.

2) Interface with 4-bits MPU
When interfacing data length aref 4-bits , 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~DB7) are transferred, and then the lower 4-bit
(in case of 8-bit bus mode, the contents of DB0~DB3) are transferred. So transfer is performed in two parts. Busy
Flag outputs"1" after the second transfer are ended.

work under dry conditions.
-The
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
).Whenever possible, the
Modules
should be stored in the same conditions in which they were shipped from our company.
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 , 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.
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 Modules.
-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

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
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. 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
