Clear Display RS 0 R/W DB7 0 0 DB6 0 DB5 0 DB4 0 DB3 0 DB2 0 DB1 0 DB0 1 Clear all the display data by writing 20H (space code) to all DDRAM address, and set DDRAM address to 00H into AC (address counter). Return cursor to the original status, namely, bring the cursor to the left edge on the first line of the display. Make the entry mode increment ( I/D = HIGH ) B. Return Home RS R/W DB7 DB6 DB5 DB4 DB3 DB2 0 0 0 0 0 0 0 0 DB1 1 DB0 - Set DDRAM address to 00H into the address counter. Return cursor to its original site and return display to its original status,if shifted. Contents of DDRAM does not change. C. Entry Mode Set RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 0 0 0 1 I/D SH Set the moving direction of cursor and display. I/D:Increment /decrement of DDRAM address(cursor or blink) I/D=High,cursor/blink moves to right and DDRAM address is increased by 1. I/D=low,cursor/blink moves to left and DDRAM address is decreased by 1. *CGRAM operates the same way as DDRAM, when reading from or writing to CGRAM. SH:Shift of entire display When DDRAM read (CGRAM read/write) operation or SH=Low,shifting of entire display is not performed.if SH=High, and DDRAM write operation,shift of entire display is performed according to I/D value(I/D=High,shift left, I/D=Low, shift right). BOOKBINDING AREA MODE NO. PRODUCT SPEC. PAGE 12/20 D. Display ON/OFF Control RS R/W 0 0 DB7 0 DB6 0 DB5 DB4 DB3 DB2 DB1 DB0 0 0 1 D C B D:Display ON/OFF control bit When D=High, entire display is turned on. When D=Low, display is turned off, but display data remains in DDRAM. C:Cursor ON/OFF control bit When C=High, cursor is turned on. When C=Low, cursor is disappeared in current display ,but I/D register preserves its data. B:Cursor Blink ON/OFF control bit When B=High, cursor blink is on, which performs alternately between all the High data and display characters at the cursor position. When B=Low ,blink is off. E. Cursor or Display Shift RS R/W 0 0 DB7 0 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 1 S/C R/L - - Shifting of right/left cursor position or display without writing or reading of display data. This instruction is used to correct or search display data. nd st th During 2-line mode display, cursor moves to the 2 line after the 40 digit of the 1 line. Note that display shift is performed simultaneously in all the lines. When displayed data is shifted repeatedly, each line is shifted individually. When display shift is performed, the contents of the address counter are not changed. S/C R/L Operation 0 0 Shift cursor to the left, AC is decreased by 1 0 1 Shift cursor to the right, AC is increased by 1 1 0 Shift all the display to the left,cursor moves according to the display 1 1 Shift all the display to the right,cursor moves according to the display BOOKBINDING AREA MODE NO. PRODUCT SPEC. F. Function set RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 1 DL N F - - DL:Interface data length control bit When DL=High, it means 8-bit bus mode with MPU. When DL=Low, it means 4-bit bus mode with MPU. When 4-bit bus mode, it needs to transfer 4-bit data twice. N:Display line number control bit When N=Low, 1-line display mode is set. When N=High, 2-line display mode is set. F:Display font type control bit When F=Low, 5x8 dots format display mode is set. When F=High, 5x11 dots format display mode. G. Set CGRAM Address RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 1 AC5 AC4 AC3 AC2 AC1 AC0 Set CGRAM address to AC. This instruction makes CGRAM data available from MPU. H. Set DDRAM Address RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 1 AC6 AC5 AC4 AC3 AC2 AC1 AC0 Set DDRAM address to AC. This instruction makes DDRAM data available from MPU. When 1-line display mode (N=Low), DDRAM address is from 00H to 4FH st In 2-line display mode(N=High),DDRAM address in the 1 line is from 00H to 27H and DDRAM address in the 2nd line is from 40H to 67H PAGE 13/20 BOOKBINDING AREA MODE NO. PRODUCT SPEC. PAGE 14/20 I. Read Busy Flag & Address RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 1 BF AC6 AC5 AC4 AC3 AC2 AC1 AC0 This instruction shows whether IC is in internal operation or not . If BF is High, internal operation is in progress and shall wait until BF is to be Low, which by then the next instruction can be performed. In this instruction you and also read the value of the address counter. J. Write data to RAM RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 0 D7 D6 D5 D4 D3 D2 D1 D0 Write binary 8-bit data to DDRAM/CGRAM. The selection of RAM from DDRAM,and CGRAM,is set by the previous address set instruction(DDRAM address set,CGRAM address set). RAM set instruction can also determine the AC direction to RAM. After write operation, the address is automatically increased /decreased by 1,according the entry mode. K. Read data from RAM RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 1 D7 D6 D5 D4 D3 D2 D1 D0 Read binary 8-bit data from DDRAM/CGRAM. The selection of RAM is set by the previous address set instruction.If the address set instruction of RAM is not performed before this instruction, the data that has been read first is invalid, as the direction of AC is not yet determined. If RAM data is read several times without RAM address instructions set before read operation,the correct RAM data can be obtained from the second. But the first data would be incorrect,as there is no time margin to transfer RAM data. BOOKBINDING AREA PRODUCT SPEC. MODE NO. PAGE 15/20 In case of DDRAM read operation,cursor shift instruction plays the same role as DDRAM address set instruction,it also transfers RAM data to output data register. After read operation,address counter is automatically increased/decreased by 1 according to the entry mode. After CGRAM read operation,display shift may not be executed correctly. Note:In case of RAM write operation,AC is increased/decreased by 1 as in read operation. At this time,AC indicates the next address position, but only the previous data can be read by the read instruction. 13.
