4) Display ON/OFF control
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0000001D CB
Control display/cursor/blink ON/OFF 1 bit register.
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 D=“High”, cursor is turned on.
When D=“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.
5) Cursor or display shift
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
000001S/CR/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. (Refer to Table 6) nd
line after the 40
th
digit of the 1
st
line.
During 2-line mode display, cursor moves to the 2
When display data is shifted repeatedly, each line is shifted individually.
When display shift is performed, the contents of the address counter are not changed.
Shift patterns according to S/C and R/L bits
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
6) Function set
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
00001DL N F- -
DL: Interface data length control bit
When DL=“High”, it mans 8-bit bus mode with MPU.
When DL=“Low”, it mans 4-bit bus mode with MPU. Hence, DL is a signal to select 8-bit or 4-bit bus mode.
When 4-but 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.
