Graphic Display Data RAM (GDDRAM)
The GDDRAM is a bit mapped static RAM holding the bit pattern
to be displayed. The size of the RAM is 132 X 65= 8580 bits. Figure
5 is a description of the GDDRAM address map. For mechanical
flexibility, re-mapping on both Segment and Common outputs can be
selected by software. For vertical scrolling of display, an internal reg-
ister storing the display start line can be set to control the portion of
the RAM data to be mapped to the display. Figure 5 shows the case
in which the display start line register is set to 38h.
