A. Clear Display
Clear all the display data by writing 20H (space code) to all DDRAM address, and set
DDRAM address to 00H into AC (address counter).
Return cursor to the original status, namely, bring the cursor to the left edge on the first line
of the display.
Make the entry mode increment ( I/D = HIGH )
B. Return Home
Return cursor to its original site and return display to its original status,if shifted.
Contents of DDRAM does not change.
C. Entry Mode Set
Set the moving direction of cursor and display.
I/D:Increment /decrement of DDRAM address(cursor or blink)
I/D=High,cursor/blink moves to right and DDRAM address is increased by 1.
I/D=low,cursor/blink moves to left and DDRAM address is decreased by 1.
*CGRAM operates the same way as DDRAM, when reading from or writing to CGRAM.
SH:Shift of entire display
When DDRAM read (CGRAM read/write) operation or SH=Low,shifting of entire
display is not performed.if SH=High, and DDRAM write operation,shift of entire display
is performed according to I/D value(I/D=High,shift left, I/D=Low, shift right).

D. Display ON/OFF Control
D:Display ON/OFF control bit
When D=High, entire display is turned on.
When D=Low, display is turned off, but display data remains in DDRAM.
C:Cursor ON/OFF control bit
When C=High, cursor is turned on.
When C=Low, cursor is disappeared in current display ,but I/D register preserves its data.
B:Cursor Blink ON/OFF control bit
and display characters at the cursor position.
WhenB=Low,blinkisoff.
E. Cursor or Display Shift
Shifting of right/left cursor position or display without writing or reading of display data.
This instruction is used to correct or search display data.
During 2-line mode display, cursor moves to the 2
ndline after the 40th
digit of the 1st line.
Note that display shift is performed simultaneously in all the lines.
When displayed data is shifted repeatedly, each line is shifted individually.
When display shift is performed, the contents of the address counter are not changed.

When DL=High, it means 8-bit bus mode with MPU.
When DL=Low, it means 4-bit bus mode with MPU.
When 4-bit bus mode, it needs to transfer 4-bit data twice.

Set CGRAM address to AC.
This instruction makes CGRAM data available from MPU.
H. Set DDRAM Address
Set DDRAM address to AC.
This instruction makes DDRAM data available from MPU.

you and also read the value of the address counter.
J. Write data to RAM
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,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 the
entry mode.
K. Read data from RAM
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 has been read
first is invalid, as the direction of AC is not yet determined. If RAM data is read several
times without RAM address instructions set before read operation,the correct RAM data
can be obtained from the second. But the first data would be incorrect,as there is no time
margin to transfer RAM data.

In case of DDRAM read operation,cursor shift instruction plays the same role as DDRAM
address set instruction,it also transfers 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.
Note:In case of RAM write operation,AC is increased/decreased by 1 as in read operation.
At this time,AC indicates the next address position, but only the previous data can be read
by the read instruction.

If Interface Data Is 8-bits Long If Interface Data Is 4-bit Long
Data transfer is made through all 8 bus lines from
DB0 to DB7
Data transfer is accomplished through 4 bus lines
from DB4 to DB7.(while the rest of 4 bus lines from
DB0 toDB3 are not used.)
Data transfer is completed when 4-bits of data is
transferred twice.(upper 4-bits of data, then lower
4-bits of data.)
Features
1. Interface to an 8-bit or 4-bit MPU is available.
2. 192 types of alphanumeric, symbols and special characters can be displayed with the
built - in character generator (ROM).
3. Other preferred characters can be displayed by character generator (RAM).
4. Various instructions may be programmed.
Clear display
Cursor at home
On/Off cursor
Blink character
Shift display
Shift cursor
Read/Write display data .etc.
5. Compact and light weight design which can easily be integrated into end products.
6. Single power supply +5V drive (except for extended temperature type).
7. Low power consumption.
