Instruction Set 1 continued Instruction Instruction Code Description Execution time RE RS R/ W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 (fosc=270kHz) Set CGRAM Address 0 0 0 0 1 AC5 AC4 AC3 AC2 AC1 AC0 Set CGRAM address in address counter. 39 µs Set SEGRAM Address 1 0 0 0 1 X X AC3 AC2 AC1 AC0 Set SEGRAM address in address counter. 39 µs Set DDRAM Address 0 0 0 1 AC6 AC5 AC4 AC3 AC2 AC1 AC0 Set DDRAM address in address counter. 39 µs Set Scroll Quantity 1 0 0 1 X SQ 5 SQ 4 SQ 3 SQ 2 SQ 1 SQ 0 Set the quantity of horizontal dot scroll. 39 µs Read Busy flag and Address x 0 1 BF AC6 AC5 AC4 AC3 AC2 AC1 AC0 Can be known whether during internal operation or not by reading BF. The contents of address counter can also be read. BF = “1” : busy state, BF = “0” : ready state. 0 µs Write Data X 1 0 D7 D6 D5 D4 D3 D2 D1 D0 Write data into internal RAM (DDRAM / CGRAM / SEGRAM). 43 µs Read Data X 1 1 D7 D6 D5 D4 D3 D2 D1 D0 Read data from internal RAM (DDRAM / CGRAM / SEGRAM). 43 µs NOTE: When an MPU program with Busy Flag (DB7) checking is mode, 1/2 fOSC is necessary for executing the next instruction by the falling edge of the "E" signal after the Busy Flag (DB7) goes to "low".
