Instruction Description
Clear Display
Return Home
Entry Mode Set
I/D : Increment / decrement of DDRAM address (cursor or blink)
S: Shift of entire display
When I/D = "High", cursor/blink moves to right and DDRAM address is increased by 1.
When I/D = "Low", cursor/blink moves to left and DDRAM address is decreased by 1.
* CGRAM operates the same as DDRAM, when read from or write to CGRAM.
When DDRAM read (CGRAM read/write) operation or S = "Low", shift of entire display is not performed. If
S = "High" and DDRAM write operation, shift of entire display is performed according to I/D value (I/D =
"1" : shift left, I/D = "0" : shift right).
