Graphics Operation Processing
1.
Write mode 1: AM = 0, LG2-0 = “000”
This mode is used when the data is horizontally written at high speed. It can also be used to initialize
the graphics RAM ( GRAM ) or to draw borders. The write-data mask function ( WM15-0 ) are also
enabled in these operations. 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
below after it has reached the left or right edge of the GRAM.
