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})
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

the display image.
interface) display RAM column address so this function will only take effect after rewriting the RAM data.

UC1682 supports on-chip swapping of R
The definition of R/G/B input data is determined by LC[7:6], as described in Set Color Mode below.

LC[2] controls Mirror Y (MY): MY is implemented by reversing the mapping order between RAM and
LC[1] controls Mirror X (MX): MX is implemented by selecting the CA or 103-CA as write/read (from host
