The contents of DDRAM are not changed. 1.53 ms Entry Mode SET 0 0 0 0 0 0 0 1 I/D SH Assign cursor moving direction and enable the shift of entire display. 39 µS Display ON/OFF Control 0 0 0 0 0 0 1 D C B Set display (D), cursor (C), and blink of cursor (B) on/off control bit. 39 µS Cursor or Display Shift 0 0 0 0 0 1 S/ C R/ L -- -- Set cursor moving and display shift control bit, and the direction, without changing of DDRAM data. 39 µS Function Set 0 0 0 0 1 DL N F -- -- Sets interface data length (DL:8-bit/4-bit), number of display lines (N:2-line/1-line) and , display font type (F:5x11dots/5x8 dost). 39 µS Set CG RAM Address 0 0 0 1 AC 5 AC 4 AC 3 AC 2 AC 1 AC 0 Sets CG RAM address in address counter. 39 µS Set DD RAM Address 0 0 1 AC 6 AC 5 AC 4 AC 3 AC 2 AC 1 AC 0 Sets DD RAM address in address counter. 39 µS Read Busy Flag and Address 0 1 BF AC 6 AC 5 AC 4 AC 3 AC 2 AC 1 AC 0 Whether during internal operation or not can be known by reading BF. The contents of address counter can also be read. 0 µS Write Data to RAM 1 0 D7 D6 D5 D4 D3 D2 D1 D0 Writes data into internal RAM (DD RAM /CG RAM). 43 µS Read Data from RAM 1 1 D7 D6 D5 D4 D3 D2 D1 D0 Reads data from internal RAM (DD RAM /CG RAM). 43 µS * “--“ : don’t care Note : When an MPU program with checking the Busy Flag(DB7) is made, it must be necesssary1/2Fosc is necessary for executing the next instruction by the falling edge of the ‘E’ signal after the Busy Flag(DB7) goes to “LOW”.
