11.Instruction description
11.1Outline
To overcome the speed difference between the internal clock of KS0066U and the MPU clock, KS0066U
performs internal operations by storing control in formations to IR or DR. The internal operation is determined
according to the signal from MPU, composed of read/write and data bus (Refer to Table7).
Instructions can be divided largely into four groups:
1) KS0066U 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 “High”.
Busy flag check must be preceded by the next instruction.

When I/D=“high”, cursor/blink moves to right and DDRAM address is increased by 1.
When I/D=“Low”, cursor/blink moves to left and DDRAM address is increased 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”.

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 2nd line after the 40th digit of the 1st line.
Note that display shift is performed simultaneously in all the lines.
When display 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=“Low”, it means 4-bit bus mode with MPU. Hence, DL is a signal to select 8-bit or 4-bit bus mode.
When 4-but bus mode, it needs to transfer 4-bit data twice.
N: Display line number control bit
When N=“Low”, 1-line display mode is set.
When N=“High”, 2-line display mode is set.

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).

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 next address position, but only the previous data can be read by the read
instruction.

14.4 Precaution for using LCD/LCM
LCD/LCM is assembled and adjusted with a high degree of precision. Do not attempt to make
any alteration or modification. The followings should be noted.
General Precautions:
1. LCD panel is made of glass. Avoid excessive mechanical shock or applying strong
pressure onto the surface of display area.
2. The polarizer used on the display surface is easily scratched and damaged. Extreme care
should be taken when handling. To clean dust or dirt off the display surface, wipe gently
with cotton, or other soft material soaked with isoproply alcohol, ethyl alcohol or
trichlorotriflorothane, do not use water, ketone or aromatics and never scrub hard.
3. Do not tamper in any way with the tabs on the metal frame.
4. Do not make any modification on the PCB without consulting Newhaven Display
5. When mounting a LCM, make sure that the PCB is not under any stress such as bending
or twisting. Elastomer contacts are very delicate and missing pixels could result from
slight dislocation of any of the elements.
6. Avoid pressing on the metal bezel, otherwise the elastomer connector could be deformed
and lose contact, resulting in missing pixels and also cause rainbow on the display.
7. Be careful not to touch or swallow liquid crystal that might leak from a damaged cell. Any liquid crystal
adheres to skin or clothes, wash it off immediately with soap and water.
Static Electricity Precautions:
1. CMOS-LSI is used for the module circuit; therefore operators should be grounded whenever
he/she comes into contact with the module.
2. Do not touch any of the conductive parts such as the LSI pads; the copper leads on the PCB and
the interface terminals with any parts of the human body.
3. Do not touch the connection terminals of the display with bare hand; it will cause disconnection or

defective insulation of terminals.
The modules should be kept in anti-static bags or other containers resistant to static for storage.
Only properly grounded soldering irons should be used.
If an electric screwdriver is used, it should be grounded and shielded to prevent sparks.
The normal static prevention measures should be observed for work clothes and working
benches.
8. Since dry air is inductive to static, a relative humidity of 50-60% is recommended.

7.
Soldering Precautions:
1. Soldering should be performed only on the I/O terminals.
2.
3.
4.
5.
6.
7.
Use soldering irons with proper grounding and no leakage.
Soldering temperature: 280qC+10qC
Soldering time: 3 to 4 second.
Use eutectic solder with resin flux filling.
If flux is used, the LCD surface should be protected to avoid spattering flux.
Flux residue should be removed.
Operation Precautions:
1. The viewing angle can be adjusted by varying the LCD driving voltage Vo.
2. Since applied DC voltage causes electro-chemical reactions, which deteriorate the
display, the applied pulse waveform should be a symmetric waveform such that no DC
component remains. Be sure to use the specified operating voltage.
3. Driving voltage should be kept within specified range; excess voltage will shorten display
life.
4. Response time increases with decrease in temperature.
5. Display color may be affected at temperatures above its operational range.
6.
7.
Keep the temperature within the specified range usage and storage. Excessive temperature
and humidity could cause polarization degradation, polarizer peel-off or generate bubbles.
For long-term storage over 40qC is required, the relative humidity should be kept below 60%,
and avoid direct sunlight.
Limited Warranty
Newhaven Display LCDs and modules are not consumer products, but may be incorporated by Newhaven
Display’s customers into consumer products or components thereof, Newhaven Display does not warrant that
its LCDs and components are fit for any such particular purpose.

3.
Newhaven display will not be responsible for any subsequent or consequential events or injury or
damage to any personnel or user including third party personnel and/or user. Unless otherwise agreed in
writing between Newhaven Display and the customer, Newhaven Display will only replace or repair any of
its LCD which is found defective electrically or visually when inspected in accordance with Newhaven
Display general LCD inspection standard . (Copies available on request)
No warranty can be granted if any of the precautions state in handling liquid crystal display above
has been disregarded. Broken glass, scratches on polarizer mechanical damages as well as defects that
are caused accelerated environment tests are excluded from warranty.
In returning the LCD/LCM, they must be properly packaged; there should be detailed description of
the failures or defect.
