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. 11.2 Instruction Table Instruction code Instruction RS DB R/W DB7 DB6 5 DB DB4 DB3 DB2 1 DB0 Clear Display 0 0 0 0 0 0 0 0 0 1 Return Home 0 0 0 0 0 0 0 0 1 - Entry mode Set 0 0 0 0 0 0 0 1 I/D SH Display ON/ OFF control 0 0 0 0 Cursor or Display shift 0 0 0 0 Function set 0 0 0 0 0 0 0 1 Set CGRAM Address Set DDRAM Address Read busy Flag and Address Write data to Address Read data From RAM 0 0 1 Execution time (fosc= 270 KHZ Description Write “20H” to DDRA and set DDRAM address to “00H” from AC Set DDRAM address to “00H” From AC and return cursor to Its original position if shifted.

Return cursor to the original status, namely, bring the cursor to the left edge on the fist line of the display. Make the entry mode increment (I/D=“High”). 2) Return home RS R/W DB7 DB6 DB5 DB4 DB3 DB2 0 0 0 0 0 0 0 0 Return home is cursor return home instruction. Set DDRAM address to “00H” into the address counter. Return cursor to its original site and return display to its original status, if shifted. Contents of DDRAM does not change. 3) Entry mode set RS R/W 0 0 DB7 0 DB6 0 DB5 0 DB4 0 DB3 0 DB2 1 DB1 1 DB0 - DB1 I/D DB0 SH Set the moving direction of cursor and display. I/D: increment / decrement of DDRAM address (cursor or blink) 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”. shift left, I/D=“Low”. Shift right). 4) Display ON/OFF control RS R/W DB7 DB6 DB5 0 0 0 0 0 Control display/cursor/blink ON/OFF 1 bit register. DB4 0 DB3 1 DB2 D DB1 C DB0 B 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 D=“High”, cursor is turned on. When D=“Low”, cursor is disappeared in current display, but I/D register preserves its data. B: Cursor blink ON/OFF control bit When B=“High”, cursor blink is on, which performs alternately between all the “High” data and display characters at the cursor position. When B=“Low”, blink is off. 5) Cursor or display shift RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 0 0 0 0 0 1 S/C R/L 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. 10 2006-12-4 DB0 - Newhaven Display NHD-0216K1Z-NS(RGB)-FBW 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. Shift patterns according to S/C and R/L bits S/C 0 0 1 1 6) R/L 0 1 0 1 Function set RS R/W 0 0 Operation Shift cursor to the left, AC is decreased by 1 Shift cursor to the right, AC is increased by 1 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 DB7 0 DB6 0 DB5 1 DB4 DL DB3 N DB2 F DB1 - DB0 - DL: Interface data length control bit When DL=“High”, it means 8-bit bus mode with MPU. 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. F: Display line number control bit When F=“Low”, 5x8 dots format display mode is set. When F=“High”, 5x11 dots format display mode. 7) Set CGRAM address RS R/W DB7 0 0 0 DB6 1 DB5 AC5 DB4 AC4 DB3 AC3 DB2 AC2 DB1 AC1 DB0 AC0 DB4 AC4 DB3 AC3 DB2 AC2 DB1 AC1 DB0 AC0 Set CGRAM address to AC. The instruction makes CGRAM data available from MPU. 8) Set DDRAM address RS R/W DB7 0 0 1 DB6 AC6 DB5 AC5 Set DDRAM address to AC. This instruction makes DDRAM data available form MPU. When 1-line display mode (N=LOW), DDRAM address is form “00H” to “4FH”.In 2-line display mode (N=High), DDRAM address in the 1st line form “00H” to “27H”, and DDRAM address in the 2nd line is from “40H” to “67H”. 9) Read busy flag & address RS R/W DB7 0 1 BF DB6 AC6 DB5 AC5 DB4 AC4 DB3 AC3 DB2 AC2 DB1 AC1 DB0 AC0 This instruction shows whether KS0066U is in internal operation or not. If the resultant BF is “High”, internal operation is in progress and should wait BF is to be LOW, which by then the nest instruction can be performed. In this instruction you can also read the value of the address counter. 10) Write data to RAM RS R/W DB7 1 0 D7 DB6 D6 DB5 D5 DB4 D4 DB3 D3 DB2 D2 DB1 D1 Write binary 8-bit data to DDRAM/CGRAM. 11 2006-12-4 DB0 D0 Newhaven Display NHD-0216K1Z-NS(RGB)-FBW 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 to the entry mode. 11) Read data from RAM RS R/W DB7 1 1 D7 DB6 D6 DB5 D5 DB4 D4 DB3 D3 DB2 D2 DB1 D1 DB0 D0 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. 12.

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 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. 20 2006-12-4 Newhaven Display NHD-0216K1Z-NS(RGB)-FBW 3. Do not touch the connection terminals of the display with bare hand; it will cause disconnection or defective insulation of terminals. 4. The modules should be kept in anti-static bags or other containers resistant to static for storage. 5. Only properly grounded soldering irons should be used. 6. If an electric screwdriver is used, it should be grounded and shielded to prevent sparks. 7. 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. 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 LCDs and modules are not consumer products, but may be incorporated by NEWHAVEN’S customers into consumer products or components thereof, NEWHAVEN does not warrant that its LCDs and components are fit for any such particular purpose. 1. 2. 3. The liability of NEWHAVEN is limited to repair or replacement on the terms set forth below. NEWHAVEN 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 and the customer, NEWHAVEN will only replace or repair any of its LCD which is found defective electrically or visually when inspected in accordance with NEWHAVEN 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. 21 2006-12-4
