HD66730/HD66731
An example of displaying full-size and half-size characters together is described here.
Full-size character display conforms to JIS (16 bits). Perform code conversion (16 bits → 12 bits)
according to the relationship between the 16-bit JIS code and the HD66730/1 12-bit character code and
write two-byte character data to the DDRAM (write the lower byte to the smaller DDRAM address). The
example is shown in Table 19. When displaying a half-size character, refer to Table 5 the HD66730/1 Half-
size Font List and write one-byte character data into the DDRAM. The example is shown in Table 20.
Figure 24 shows how to set data to the DDRAM when performing a 2-line display and Figure 25 shows the
resulting liquid crystal display.
