Entry Mode Set Instruction
The Entry Mode Set Instruction has two controlling bits: I/D and S. Please refer to the table below.
RS R/WB DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 0 0 0 1 I/D S
I/D is the Increment / Decrement Bit.
When I/D is set to "1". the DDRAM Address is incremented by "1" when a character code is written
into or read from the DDRAM. An increment of 1 will move the cursor or blinking one step to the
right.
When the I/D is set to "0", the DDRAM is decremented by 1 when a character code is written into or
read from the DDRAM. An decrement of 1 will move the cursor or blinking one step to the left.
S : Shift Entire Display Control Bit
This bit is used to shift the entire display. When S is set to "1", the entire display is shifted to the right
(when I/D ="0") or left (when I/D ="1"). The display does not shift when reading from the DDRAM,
writing into or reading from the CGRAM. When S is set to "0", the display is not shifted.
Display ON / OFF Control Instruction
The Display On / OFF Instruction is used to turn the display ON or OFF. The controlling bits are D,
C and B.
RS R/WB DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 0 0 0 DCB
D : Display ON /OFF Bit
When D is set to "1", the display is turned ON. When D is set to "0", the display is turned OFF and
the display data is stored in the DDRAM. The display data can be instantly displayed by setting D to
"1".
C : Cursor Display Control Bit
When C is set to "1", the cursor is displayed. In a 5 x 8 dot character font, the cursor is displayed via
the 5 dots in the 8th line. In a 5 x 10 dot character font , it is displayed via 5 dots in the 11th line.
When C is set to "0", the cursor display is disabled.
