3. Write mode 3: AM = 0, LG2–0 = 110/111
This mode is used when data are horizontally written with comparing the write data and the value set in the
compare register (CP17–0) by R, G, B pixel. When the result of the comparison satisfies a condition, the
write data sent from the microcomputer are written to GRAM. In this operation, the write-data mask
function (WM17–0) is available. After writing, the address counter (AC) automatically increments by 1
(I/D = 1) or decrements by 1 (I/D = 0), and jumps to the counter at the opposing edge of the next one-
raster-row below after when the counter reaches either left or right edge of GRAM.

GRAM
Data are expanded into 18 bits in 8/16-bit system
interface, and 16-bit RGB interface modes.
Operation example
1) I/D = "1", AM = "0", LG2-0 = "110" (matched writing)
2)CP17-0 = "050C0"H
3)WM17-0 = "00000"H
