RAM for display (addresses 0600
16
to 06D7
16
)
The CRT display RAM is allocated at addresses 0600
16
to 06D7
16
,
and is divided into a display character code specification part and
display color specification part for each block. Table 9 shows the
contents of the CRT display RAM.
For example, to display 1 character position (the left edge) in block
1, write the character code in address 0600
16
and write the color
register No. to the low-order 2 bits (bits 0 and 1) in address 0680
16
.
The color register No. to be written here is one of the 4 color regis-
ters in which the color to be displayed is set in advance. For details
on color registers, refer to (5) Color Registers. The structure of the
CRT display RAM is shown in Figure 53.
