The following commands are executed during initialization. The busy flag is kept in the busy state until initialization is complete. The busy state lasts for 10 ms after VDD reaches 4.5 volts. 1) Clear Display 2) Function set DL=1.......8-bit data length for interface N=0.........Single-line display F=0.........5x7 dot matrix character font 3) Display ON/OFF Control D=0........Display OFF C=0........Cursor OFF B=0........Blink function OFF 4) Entry Mode Set I/D=1......Increment Mode S=0........Display shift OFF NOTE: If the following power conditions are not satisfied, the internal reset circuit does not function properly. In this case, the initialization should be executed by the series of instructions from outside the MPU (Software Initialization).

This will insure that the internal electronics have time to begin operation before the negative voltage is applied. The sequence of events should be as follows: Apply V DD first. When VDD is stable at 5v, apply the input signals and then apply V L/VEE. The shut down sequence is exactly the opposite. Failure to follow this procedure may result in permanent damage to the LCD fluid or to the CMOS electronics on the module. 1second min 1 second min 5v VDD 0v 0 to 50mS 0 - 50mS 5v INPUT SIGNALS 0v 0 sec min 0 sec min VL/VEE 0v Minus v NOTICE: Specifications in this catalog are subject to change without notice.
