(4) Memory for Display
There are 2 types of memory for display : CRT display ROM (ad-
dresses 1000016 to 11FFF16) used to store character dot data
(masked) and CRT display RAM (addresses 060016 to 06B716) used
to specify the colors of characters to be displayed. The following de-
scribes each type of display memory.
ROM for display (addresses 1000016 to 11FFF16)
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 determined based on the addresses in the
CRT display ROM) into the CRT display RAM. The character code
list is shown in Table 10.
The CRT display ROM has a capacity of 8K bytes. Since 32 bytes
are required for 1 character data, the ROM can stores up to 256
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 and 1100016 to
117FF16 ; the [vertical 16 dots] ! [horizontal (right side) 4 dots] data
of display characters are stored in addresses 1080016 to 10FFF16
and 1180016 to 11FFF16 (refer to Figure 40). Note however that the
high-order 4 bits in the data to be written to addresses 1080016 to
10FFF16 and 1180016 to 11FFF16 must be set to “1” (by writing data
“FX16”).
