Clear Display RS R/W DB7 DB6 DB5 0 0 0 0 0 This instruction is used to clear the display by writing 0x20 in all DDRAM addresses. This instruction does not change the DDRAM Address. Return Home RS R/W DB7 DB6 DB5 0 0 0 0 0 This instruction is used to set the DDRAM Address to 0x00 and shifts the display back to the original state. The cursor (if on) will be at the first line’s left‐most character. The DDRAM contents on the display do not change. Entry Mode Set RS R/W DB7 DB6 DB5 0 0 0 0 0 I/D = Increment/Decrement ...

C = Cursor ON/OFF When C = “1”, the cursor is displayed. The cursor is displayed as 5 dots on the 8 cursor is OFF. B = Blinking Cursor When B = “1”, the entire character specified by the cursor blinks at a speed of 409.6ms intervals. When B = “0”, the character does not blink, the cursor remains on.

Set CGRAM Address RS R/W DB7 DB6 DB5 0 0 0 1 ACG5 This instruction is used to set the CGRAM address into the Address Counter. Data can then be written to or read from the CGRAM locations. See section: “How to use CGRAM”. ACG5..ACG0 is the binary CGRAM address. Set DDRAM Address RS R/W DB7 DB6 DB5 0 0 1 ADD6 ADD5 ADD4 ADD3 This instruction is used to set the DDRAM address into the Address Counter. Data can then be written to or read from the DDRAM locations. ADD6..ADD0 is the binary DDRAM address. Line 1 = Address 0x00 through 0x13 Line 2 = Address 0x40 through 0x53 Line 3 = Address 0x14 through 0x27 Line 4 = Address 0x54 through 0x67 1 2 3 ...

This instruction is used to read 8‐bits of data to the CGRAM or DDRAM at the current address counter. After the read is complete, the address is automatically incremented or decremented by 1 according to the Entry Mode. The Set CGRAM Address or Set DDRAM Address Instruction must be executed before this instruction can be performed, otherwise the first Read Data will not be valid. MPU Interface When DL is set for 8‐bit mode, the display interfaces with the MPU with DB7..DB0 (DB7 is the MSB). When DL is set for 4‐bit mode, the display interfaces with the MPU with only DB7..DB4 (DB7 is the MSB). Each instruction must be sent in two operations, the 4 high‐order bits first, followed by the 4 low‐order bits. The Busy Flag must be checked after completion of the entire 8‐bit instruction. 6800‐MPU Parallel Interface (default) AS68 CSB 0.

How to use CGRAM The Character Generator RAM (CGRAM) is used to generate custom 5x8 character patterns. There are 8 available addresses: CGRAM Address 0x00 through 0x08. Character Code DDRAM address on Font Table used to write CGRAM Address CGRAM character to display 5 4 0 0 0x00 0 0 0x01 . . . . 0x02..0x06 . . . . 1 1 1 0x07 Notes: “‐“ = Not used The cursor line position can be used, it will be displayed as a logic‐OR if the cursor is turned ON. CGRAM is stored in positions 0x00 through 0x07 of the font table. Therefore, to write the first CGRAM character to the display, you would move the cursor to the desired DDRAM location on the display and write character data 0x00. ...
