Instruction Data Format Additional Serial Data Commands
Set RS Low 0FH Set the RS line low for the following byte only. Used in serial communications only.
Read Data FEH Read data at current cursor position. This command is used with serial communications only.
Read Cursor Position FFH Read current cursor position. This command is used with serial communications only.
Notes: - 1. When display shift is enabled, the data write busy time can increase by 150us.
2. If the cursor is enabl ed, busy times can increase by 20us.
3. After these commands are executed, the cursor will be disabled and any character data will be written to the display only, and not the DD RAM. Any
subsequent LCD compatible command wi ll re-enable the cursor and allow for DD RAM writing.

When using the graphical data commands (F0H, F1H & F2H), data is written direct to the display and is not

counter is incremented. If set to ‘0’, the address counter is decremented.
Bit 0 enables the display to shift on each data read/write. If this bit is set to ‘ 1’, the display is shifted with the
cursor. The display shift direction depends upon the address counter direction (bi t1). If this is set to
increment, the display is shifted left, if the address counter is set to decrement, the display is shifted right.
reduce power consumption.
Bit 0 enables the flashing block cursor.
10H Shift the cursor position (address counter) one position to the left.
14H Shift the cursor position (address counter) one position to the right.
18H Shift the display left, one character position.
1CH Shift the display right, one character position.
20H + lum Enables 4-bit communi cations. Data is received on DB4-DB7 only. Two writes are required to send one data
30H + lum Enables 8-bit communications. Data is received on DB0-DB7.
40H – 7FH Set the character generator address (CG RAM). All written data is placed within the user definable character
byte. The most significant nibble should be sent first.
The lum value sets the displays brightness, 00H = full brightness, 01H = 75%, 02H = 50% & 03H = 25%.

F0H + xpos + ypos Set the absolute cursor position. xpos = 0 – 111, ypos = 0 – 15.
F1H + x1 + y1 + x2 + y2 + cmd Area Commands: - ‘I’ - invert area. ‘F’ – fill area. ‘C’ = clear area. ‘O’ – set outline. ‘o’ – clear outline.
F2H + font Select font type, font size and font spacing.
Co-ordinates should be written with RS line set hi gh.
‘H’ – write horizontal graphical data with horizontal cursor movement.
‘V’ – write vertical graphical data with horizontal cursor movement.
‘h’ – write horizontal graphical data with vertical cursor movement.
All area commands should be proceeded with the area co-ordinates. X1 X2 left top X2 Y2 bottom right
Graphical data should immediately follow the ‘H’,’h’,’V’ and ‘v’ commands.
Co-ordinates, command and graphical data should be written with RS line set high.
Font commands: - ‘A’ or ‘a’ = proportional 64 character mini-font.
Font command should be written with RS line set high.
‘v’ – write vertical graphical data with vertical cursor movement.
‘B’ = 5x7 LCD compatible font with Katakana characters.
‘C’ = 10x14 LCD compatible font with Katakana characters.
‘b’ = 5x7 international font with European characters.
‘c’ = 10x14 international font with European characters.
‘1’ = set the inter-character pixel spacing to 1 pixel.
‘2’ = set the inter-character pixel spacing to 2 pixels.
