12.2 Mapping the Display Data
The screen width and height of the LCD panel are
programmable through software. Although the maximum
screen size can be up to 1024x512, the actual supported
resolution is limited by the display buffer size, which is also
the internal RAM size, and is 10K bytes. Instead of screen
size specified by control registers, larger frame can also be
displayed via the Virtual Page Width setting. FIGURE 12-1
illustrates the relationship between the portion of a large
graphic to be displayed on the screen and the actual area
that can be seen.
Each one or two bits in the display memory correspond to a
pixel on the LCD panel. TABLE 12-2 shows the mapping of
the display data to the LCD. When clear control bit GL[0]
(LCTR[2]) and enable B/W mode, every bit of display buffer
represents one pixel on the screen. In case of setting GL[0]
and enable 4-gray-level mode, there will be two bits to
present each pixel on the screen.
When in 4-gray-level mode, there are two kinds of light
gray,1/2 and 1/3, can be selected by GL[1] (LCTR[3]).
Refer to TABLE 12-2 for the relationship of data bits and the
displayed pixel.
