If the power supply conditions for correctly operating of the internal reset circuit are not met, initialization by instruction is required. Use the procedure is next page for initialization.

7 3. Instruction Set FUNCTION R S R /W ESCRIPTION Clear isplay Clears entire display and returns the cursor to home position ( address ). Return Home x Return the cursor to the home position. Also returns the display being shifted to the original position. RAM contents remain unchanged. Entry mode set isplay ON/OFF control I / C Cursor or isplay shift Function Set L Set CG RAM address Set RAM address Read busy flag & address Write ata to CG/RAM Read ata for CG/RAM S / C R / L x S x N F x x Set cursor move direct and specifies display shift.these operations are performed during data rite/read. For normal operation, set S to zero. I/= : increment ; :decrement ;S= : accompanies display shift when data is written, for normal operation, set to zero. Set ON/OFF all display(),cursor ON/OFF(C), and blink of cursor position character(). =: ON display; :OFF display. C=: ON cursor;: OFF cursor. =: ON blink cursor; : OFF blink cursor. Move the cursor and shift the display without changing RAM contents. S/C=: isplay shift; :Cursor move. R/L=: shift to right; : shift to left. Set the interface data length (L). Number of display lines (N) and character font (F). L=: 8 bits; :4 bits. N=: 2 lines; : lines. F=: 5x dots; : 5x7 dots. EXECU. TIME (MAX.).64ms.64ms 4μs 4μs 4μs 4μs ACG Set CG RAM address.

Functionset x x Sets to 8-bit operation and selects 2-line display and 5x7 dots character font. ( Note: number of display lines and character fonts cannot be chang after this. ) isplayoff Turnoffdisplay. isplayon Turn on display and cursor Entry Mode Set CG/ RAM CG/ RAM Set mode to increment the address by one and to shift the cursor to the right, at the time of write, to the /CG RAM isplay is not shifted. S Write S. Cursor incremented by one and shift to right. SEC Write, E, and C. SetRAM SEC Set RAM address so that the cursor is propositioned at the head of the second line. SEC Write C, and R. CG/ RAM CR Cursor or x x SEC Shift only the cursor position to the left. display shift CR SEC Write O., LT.. CG/ RAM CO., LT. Entry Mode SEC Set display mode shift at the time during writing operation. Set CO., LT. EC Write x. Cursor incremented by one and shift to CG/RAM O., LT. x right. ( The display move to left. ) Write other characters. CG/ RAM ReturnHome SEC CO., LT. Return both display and cursor to the original position ( Set address to zero) bit operation ( 4-bit, line ) Function RS R/ isplay escription W power on delay initialization. No display appears. Function set Sets to 4-bit operation. In this case, operation is handled as 8-bits by initialization, and only this instruction completes with one write. Function set Sets 4-bit operation and selects -line display and 5x7 x x dot character font on and resetting is needed. ( number of display lines and character fonts cannot be changed hence after ). isplay ON/OFF Turn on display and cursor. Control Entry Mode Set CG/ RAM S same as 8-bit operation Set mode to incremented the address by one and to shift the cursor to the right, at the time of write. to the /CG RAM display is not shifted. Write S. Cursor incremented by one and shift to right. PAGE 7HJ 62A Serial)

Functional Test & Inspection Criteria 7. Sample plan Sample plan according to MIL-ST-5 level 2, and acceptance/rejection criteria is. ase on : Major defect : AQL.65 Minor defect : AQL Inspection condition Viewing distance for cosmetic inspection is 3cm with bare eyes, and under an environment of 8 lus (2W) light intensity. All direction for inspecting the sample should be within 45 against perpendicular line. 7.3 efinition of Inspection Zone in LC A C Zone A : Character / igit area Zone : Viewing area except Zone A ( Zone A + Zone = minimum Viewing area ) Zone C : Outside viewing area ( invisible area after assembly in customer s product ) Note : As a general rule, visual defects in Zone C are permissible, when it is no trouble for quality and assembly of customer s product. 7.4 Major efect 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 8HJ 62A Serial)
