SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
For matrix and halftone, a character’s number of dots in the horizontal direction increases to 14.
Figure 4 shows a display example for a case where adjacent characters have different background colors and for character code FF16.

2. Border mode
In border mode, characters are displayed with borders. (Refer to
Table 9.) In matrix and halftone modes also, characters are dis-
played with borders if the BLK register (address 2B016) is set to 1.
Table 10 lists the types of borders.

Horizontal direction bordering is only 1 dot. When the character extends to the top line of the matrix, no border is left at the top, and when the
character extends to the bottom (12th) line of the matrix, no border is left at the bottom.
