3. Write mode 3: AM = 0, LG2–0 = 110/111
This mode is used when the data is horizontally written by comparing the write data and the set value of
the compare register (CP7–0). When the result of the comparison in a byte unit satisfies the condition, the
write data sent from the microcomputer is written to the GRAM. In this operation, the swap function
(SWP) and write-data mask function (WM15–0) are also enabled. After writing, the address counter (AC)
automatically increments by 1 (I/D = 1) or decrements by 1 (I/D = 0), and automatically jumps to the
counter edge one-raster-row below after it has reached the left or right edge of the GRAM.
