(4) Memory for Display
There are 2 types of memory for display : CRT display ROM (ad-
dresses 1000016 to 12FFF16) used to store character dot data
(masked) and CRT display RAM (addresses 060016 to 06D716) used
to specify the colors and characters to be displayed. The following
describes each type of display memory.
ROM for display (addresses 1000016 to 12FFF16)
The CRT display ROM contains dot pattern data for characters to be
displayed. For characters stored in this ROM to be actually displayed,
it is necessary to specify them by writing the character code inherent
to each character (code based on the addresses in the CRT display
ROM) into the CRT display RAM. The character code list is shown in
Table 8.
The CRT display ROM has a capacity of 12 K bytes. Since 32 bytes
are required for 1 character data, the ROM can stores up to 384
kinds of characters.
The CRT display ROM space is broadly divided into 2 areas. The
[vertical 16 dots] ! [horizontal (left side) 8 dots] data of display char-
acters are stored in addresses 1000016 to 107FF16, 1100016 to
117FF16 and 1200016 to 127FF16 ; the [vertical 16 dots] ! [horizontal
(right side) 4 dots] data of display characters are stored in addresses
1080016 to 10FFF16, 1180016 to 11FFF16 and 1280016 to 12FFF16
(refer to Figure 52). Note however that the high-order 4 bits in the
data to be written to addresses 1080016 to 10FFF16, 1180016 to
11FFF16 and 1280016 to 12FFF16 must be set to “1” (by writing data
“FX16”).
