8.10 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
128x128x4 bits. For mechanical flexibility, re-mapping on both Segment and Common outputs can be
selected by software. The GDDRAM address maps in Table 8-5 to Table 8-9 show some examples on using
the command “Set Re-map” A0h to re-map the GDDRAM. In the following tables, the lower nipple and
higher nibble of D0 ,D1, D2, …,D8189, D8190, D8191 represent the 128x128 data bytes in the GDDRAM.
Table 8-5 shows the GDDRAM map under the following condition:

Table 8-6 shows the GDDRAM map under the following condition:
