Set Color Mask MSK [2:0]
This command is used for program MSK[2:0] which will control whether the input RGB data will be blocked
from updating RGB data in the RAM. (1: Block, 0: Normal. MSK[2:0] = {MSK_R, MSK_G, MSK_B})

MSK[2:0]
Example: Let color mode = 256 color, MSK[2:0] = 100b (MSK_R = 1, MSK_G = 0, MSK_B = 0). There is one
pixel to be updated, and the original data for the pixel is 11100110b (
RRR
-
GGG
-
BB
). Suppose the new input
RGB data is 00000000b, since
R
is masked, the data for the pixel would be updated as 11100000b.

Set LCD Mapping Control LC [2:0]
This command is used for program LC[2:0] for COM (row) mirror (MY), SEG (column) mirror (MX).

COM electrodes. The data stored in RAM is not affected by MY command. MY will have immediate effect on
the display image.
LC[2] controls Mirror Y (MY): MY is implemented by reversing the mapping order between RAM and
interface) display RAM column address so this function will only take effect after rewriting the RAM data.
LC[1] controls Mirror X (MX): MX is implemented by selecting the CA or 103-CA as write/read (from host
LC[0] controls whether the soft icon section (0~ 2xFL) is display or not during partial display mode.
