SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
MEMORY CONSTITUTION
Address 00016 to 11F16 are assigned to the display RAM, address
12016 to 12816 are assigned to the display control registers. The in-
ternal circuit is reset and all display control registers (address 12016
__
to 12816) are set to “0” when the AC pin level is “L”. And then, RAM
is not erased and be undefinited. This memory is consisted of 2
pages : page 0 memory and page 1 memory (their addresses are
common), page controlled by DAF bit of each address when writing
data. For detail, see “Data input”. Memory constitution is shown in
Figure 1 and 2.
