Instruction Description
Clear Display
Clear display writes space code (20)H (character pattern for character code (20)H must be a blank
pattern) into all DDRAM addresses. It then sets DDRAM address 0 into the address counter, and returns
the display to its original status if it was shifted. In other words, the display disappears and the cursor or
blinking goes to the left edge of the display (in the first line if 2 lines are displayed). It also sets I/D to 1
(increment mode) in entry mode. S of entry mode does not change.
Return Home
Return home sets DDRAM address 0 into the address counter, and returns the display to its original status
if it was shifted. The DDRAM contents do not change.
The cursor or blinking goes to the left edge of the display (in the first line if 2 lines are displayed). In
addition, flicker may occur in a moment at the time of this instruction issue.
Entry Mode Set
I/D: Increments (I/D = 1) or decrements (I/D = 0) the DDRAM address by 1 when a character code is
written into or read from DDRAM.
The cursor or blinking moves to the right when incremented by 1 and to the left when decremented by 1.
The same applies to writing and reading of CGRAM and SEGRAM.
S:
Shifts the entire display either to the right (I/D = 0) or to the left (I/D = 1) when S is 1 during DDRAM
write. The display does not shift if S is 0.
If S is 1, it will seem as if the cursor does not move but the display does. The display does not shift when
reading from DDRAM. Also, writing into or reading out from CGRAM and SEGRAM does not shift the
display. In a low power mode (LP = 1), do not set S = 1 because the whole display does not normally
shift.
Display On/Off Control
When extension register enable bit (RE) is 0, bits D, C, and B are accessed.
D:
The display is on when D is 1 and off when D is 0. When off, the display data remains in DDRAM,
but can be displayed instantly by setting D to 1.
C:
The cursor is displayed when C is 1 and not displayed when C is 0. Even if the cursor disappears, the
function of I/D or other specifications will not change during display data write. The cursor is displayed
using 5 dots in the 8th line for 5
×
8 dot character font.
