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
erased.
Memory constitution is shown in Figure 1.
SCREEN CONSTITUTION
The screen lines and rows are determined from each address of the
display RAM. The screen constitution is shown in Figure 2.
