Initialization of LCM The LCM automatically initializes ( reset ) when power is turned on using the internal reset circuit. 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. Internal Power Supply reset 4.5V Vcc.2V toff trcc (Note ) ms trcc. ms, toff ms. (Note 2) toff stipulates the time of power OFF for momentary power supply dip or when power supply cycles ON and OFF.

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 F 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. ACG Set CG RAM address. CG RAM data is sent and received after this setting. A Set RAM address. RAM data is sent and received after this setting Reads usy Flag (F) indicating internal operation is AC being performed and reads address counter contents.

T Write T. Cursor incremented by one and shift to right. TEST Write E, S, and T. Set RAM TEST Set RAM address so that the cursor is propositioned at the head of the second line. Write data to CG/ RAM TEST CR Write C, and R. Cursor or display shift x x TEST CR Shift only the cursor position to the left. Write data to CG/ RAM TEST WORS_ Write WORS. Entry Mode TEST Set display mode shift at the time during writing operation. Set WORS Write data to TEST Write x. Cursor incremented by one and shift to CG/ RAM WORS x right. ( The display move to left. ) Write data to CG/ RAM Write other characters. Return Home TEST WORS x. Return both display and cursor to the original position ( Set address to zero).
