Instruction
ST7036
There are four categories of instructions that:
(when “EXT” option pin connect to V
Note:
Be sure the ST7036 is not in the busy state (BF = 0) before sending an instruction from the MPU to the ST7036.
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
S/C and R/L:
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
Set CGRAM address in address

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.
