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. Item Symbol Test condition Limit (Min.) Limit (Max.)

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 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).
