coordinate, Y coordinate, circle’s radius respectively.
The next two bytes are used to specify the border color.
The last two bytes are used to specify the fill color
(depends on fill option of command 0x92).
Remark:
0 ≤ A7~A0 ≤ 255; 0 ≤ B7~B0 ≤ 255; 1 ≤ C7~C0 ≤ 255
Enter the “Copy mode” by executing the command. The
following four bytes (A
D
address, start coordinates of Y address, end
coordinates or X address and the end coordinates of Y
address. The remaining two bytes (E
are used to specify the new location of X coordinates
and Y coordinates.
Remarks:
A, C ≤ 131, A < C; B, D ≤ 131, B < D
Enter the “Dim Window mode” by executing the
command 10001100. The following four bytes (A
B
coordinates of X address, start coordinates of Y
address, end coordinates or X address and the end
coordinates of Y address. The selected window area
will be dimmed by 75% white or black according to data
bit A6 of command 0x92
Remarks:
A, C ≤ 131, A < C; B, D ≤ 131, B < D
