Character Generator ROM (CGROM)
Character generator ROM (CGROM) generates 6
×
8-dot character patterns from 8-bit character codes. It
can generate 240 6
×
8-dot character patterns. Table 7 illustrates the relation between character codes and
character patterns for the Hitachi standard CGROM. User-defined character patterns are also available
using a mask-programmed ROM (see the Modifying Character Patterns section).
