• The color on the left side :

this is set to the color of the color register which is specified by bits

0 and 1 at the color specification addresses (addresses 068016 to

069716) in the CRT display RAM.

• The color on the right side :

this is set to the color of the color register which is specified by bits

2 and 3 at the color specification addresses (addresses 068016 to

069716) in the CRT display RAM.

(6) 1/2-character Unit Color Specification Mode

By setting “1” to bit 4 of CRT control register 1 (address 00EA16) it is

possible to specify colors, in units of a 1/2-character size (16 dots

high ✕ 6 dots wide), to characters in only block 1.

In the 1/2-character unit color specification mode, colors of display

characters in block 1 are specified as follows:

(7) Character Border Function

An border of 1 clock (1 dot) equivalent size can be added to a char-

acter to be displayed in both horizontal and vertical directions. The

border is output from the OUT pin.

Border can be specified in units of block by using the border selec-

tion register (address 00E516). The setting of the border takes prior-

ity of the setting by bit 5 of the color register, however, the border of

the character to which a background color has been set cannot be

output. Figure 58 shows the border selection register. Table 12 shows

the relationship between the values set in the border selection regis-

ter and the character border function.
