ST7066U
!" Instructions
There are four categories of instructions that:
#" Designate ST7066U functions, such as display format, data length, etc.
#" Set internal RAM addresses
#" Perform data transfer with internal RAM
#" Others
Instruction Table:
Note:
Be sure the ST7066U is not in the busy state (BF = 0) before sending an instruction from the MPU to the
ST7066U. If an instruction is sent without checking the busy flag, the time between the first instruction and next
instruction will take much longer than the instruction time itself. Refer to Instruction Table for the list of each
instruction execution time.

Write "20H" to DDRAM. and
set DDRAM address to
"00H" from AC
Set DDRAM address to
"00H" from AC and return
cursor to its original position
if shifted. The contents of
DDRAM are not changed.
Sets cursor move direction
and specifies display shift.
These operations are
performed during data write
and read.
D=1:entire display on
C=1:cursor on
B=1:cursor position on
Set cursor moving and
display shift control bit, and
the direction, without
changing DDRAM data.
DL:interface data is 8/4 bits
N:number of line is 2/1
F:font size is 5x11/5x8
Set CGRAM address in
address counter
Set DDRAM address in
address counter
Whether during internal
operation or not can be
known by reading BF. The
contents of address counter
can also be read.
