Fig. 20-6 Character Pattern Data Configuration
(a) Data for a character with no rimming
(b) Data for a character with rimming
If 2 is to be displayed, the character pattern is set as shown in Fig. 20-7. 0 and 1 in the pattern data correspond
to ■■ and ■, respectively. In addition, the character size, position, and color are specified by the control data.
Fig. 20-8 shows an example of the pattern of a character with rimming.
