Sets the page (X address) of RAM at the page (X address) register. Sets the Y address at the Y address counter. Reads the status. RESET 1:Reset, 0:normal. ON/OFF 1: Display OFF, 0: Display ON. BUSY 1: In operation. 0: Ready Writes data (DB0~7) into display data RAM. After writing instruction, Y address is increased by 1 automatically. Reads data (DB0~7) from display data RAM to the data bus. 11. Description Of Instructions (1) Display ON/OFF Code R/W 0 D/I 0 DB7 0 DB6 0 DB5 1 DB4 1 DB3 1 DB2 1 DB1 1 DB0 D The display data appears when D is 1 and disappers when D is 0. Though the data is not on the screen width D=0, it remains in the display data RAM. Therefore, you can make it appear by changing D=0 or D=1. (2) Code Display start line R/W 0 D/I 0 DB7 1 DB6 1 DB5 A DB4 A DB3 A DB2 A DB1 A DB0 A Z address AAAAAA (binary) of the display data RAM is set at the display start line register and displayed at the top of the screen. (3) Set page (X address) Code R/W 0 D/I 0 DB7 1 DB6 0 DB5 1 DB4 1 DB3 1 X address AAA (binary) of the display data RAM is set at the X address register. MPU is executed in this specified page until the next page is set. (4) Code DB2 A DB1 A DB0 A After that, writing or from Set Y address R/W 0 D/I 0 DB7 0 DB6 1 DB5 A DB4 A DB3 A DB2 A DB1 A DB0 A Y address AAAAAA (binary) of the display RAM is set at the Y address counter is increase by every time data is written or read to or from MPU.

No instructions are accepted while BUSY is 1, so you should make sure that BUSY is 0 before writing the next instruction. ON/OFF: This bit show the liquid crystal conditions ON condition or OFF condition. When ON/OFF is 1, the display is on OFF condition. When ON/OFF is 0, the display on ON condition. RESET: RESET=1 shows that the system is being initialized. In this condition, any instructions except Status Read instruction cannot be accepted. RESET=0 shows that initializing has finished and system is in the usual operation. (6) Write Display Data Code R/W 0 D/I 1 DB7 D DB6 D DB5 D DB4 D Writes 8-bit data DDDDDDDD (binary) into display data RAM. automatically. (7) Code DB3 D DB2 D DB1 D DB0 D The Y address is increased by 1 Read Display Data R/W 1 D/I 1 DB7 D DB6 D DB5 D DB4 D DB3 D DB2 D DB1 D DB0 D Reads out 8-bit data DDDDDDDD (binary) from the display data RAM. The Y address is increased by 1 automatically. One dummy read is necessary soon after the address setting. 12. Initializing And Programming PAGE 5 (LMG-SSC12A64 Serial) 13.

Functional Test & Inspection Criteria 14.1 Sample plan Sample plan according to MIL-STD-105D level 2, and acceptance/rejection criteria is. Base on : Major defect : AQL 0.65 Minor defect : AQL 2.5 14.2 Inspection condition Viewing distance for cosmetic inspection is 30cm with bare eyes, and under an environment of 800 lus (20W) light intensity. All direction for inspecting the sample should be within 45° against perpendicular line. 14.3 Definition of Inspection Zone in LCD C A Zone A : Zone B : Zone C : Note : B Character / Digit area Viewing area except Zone A ( Zone A + Zone B = minimum Viewing area ) Outside viewing area ( invisible area after assembly in customer’s product ) As a general rule, visual defects in Zone C are permissible, when it is no trouble for quality and assembly of customer’s product. 14.4 Major Defect All functional defects such as open ( or missing segment ), short, contrast differential, excess power consumption, smearing, leakage, etc. and overall outline dimension beyond the drawing. Are classified as major defects. PAGE 6 (LMG-SSC12A64 Serial) 14.5 Minor Defect Except the Major defects above, all cosmetic defects are classified as minor defects.
