(6) 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. In this case, set bit 5 of a color
register to “0” (character is output).
Border can be specified in units of block by using the border selec-
tion register (address 00E5
16
). Figure 45 shows the border selection
register. Table 9 shows the relationship between the values set in
the border selection register and the character border function.
