3. Write mode 3: AM = 0, LG2-0 = 110/111
This mode is used when the data is holizontally written by comparing the write data and the set value of
the compare resister ( CP7-0 ). When the result of the comparison in a byte unit satisfies the condition
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-raw below after it has reached the left or right edge of the GRAM.
