Operation (data read/write) enable signal
Four low order bi-directional three-state data bus lines.
Used for data transfer between the MPU and the LCM.
These four are not used during 4-bit operation.
Four high order bi-directional three-state data bus lines.
Used for data transfer between the MPU
Power supply for BKL (+5.0V)
Power supply for BKL (GND)

necessary for executing the next instruction by the falling edge of the “E” signal after the busy flag (DB7) goes
to “Low”.
Contents
1) Clear display
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 0 0 0 0 01
Clear all the display data by writing “20H” (space code) to all DDRAM address, and set DDRAM address
to “00H” into AC (address counter).
Return cursor to the original status, namely, bring the cursor to the left edge on the fist line of the display.
Make the entry mode increment (I/D=“High”).
2) Return home
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
000000001 -
Return home is cursor return home instruction.
Set DDRAM address to “00H” into the address counter.
Return cursor to its original site and return display to its original status, if shifted.
Contents of DDRAM does not change.
3) Entry mode set
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 0 0 0 1 I/D SH
Set the moving direction of cursor and display.
I/D: increment / decrement of DDRAM address (cursor or blink)
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 increased by 1.
*CGRAM operates the same way as DDRAM, when reading from or writing to CGRAM.
SH: shift of entire display
When DDRAM read (CGRAM read/write) operation or SH=“Low”, shifting of entire display is not performed. If
SH =“High” and DDRAM write operation, shift of entire display is performed according to I/D value. (I/D=“high”.
shift left, I/D=“Low”. Shift right).
4) Display ON/OFF control
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 0 0 1DCB
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.
