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
internal 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 con-
sisted of 2 pages : page 0 memory and page 1 memory (their ad-
dresses are common), page controlled by DAF bit of each address
when writing data. For detail, see “DATA INPUT EXAMPLE”.
Memory constitution is shown in Figure 1 and 2.
