Note : IR7, IR3 : Instruction 7th bit , 3rd bit ; AC3 : Address Counter 3rd bit.
12. 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.
