Fig. 42. Display Character Stored Data
(4) Memory for Display
There are 2 types of display memory : CRT display ROM (addresses
10000
16
to 10FFF
16
) used to store character dot data (masked) and
CRT display RAM (addresses 0600
16
to 06B3
16
) used to specify the
colors of characters to be displayed. The following describes each
type of display memory.
ROM for display (addresses 10000
16
to 10FFF
16
)
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 7.
The CRT display ROM has a capacity of 4 K bytes. Since 32 bytes
are required for 1 character data, the ROM can stores up to 128
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 10000
16
to 107FF
16
; the [vertical 16
dots]
[horizontal (right side) 4 dots] data of display characters are
stored in addresses 10800
16
to 10FFF
16
(refer to Figure 42). Note
however that the high-order 4 bits in the data to be written to ad-
dresses 10800
16
to 10FFF
16
must be set to “1” (by writing data “FX
16
”).
