contiguous addresses in the display memory space. Therefore, the CG RAM addresses to which to
write data must be calculated as follows:
• Add addresses the same way as described above (M1 = 0).
• Change bit D6 in one character code from 1 to 0 when adding addresses.
Example of CG RAM definition (method of storing data) (See Figure 4-9 “Example of display
memory mapping” on page 63.)
Conditions
Setting list
• The pattern to define: Pattern A (8 x 16 dots per font) shown in Figure 4-1 “Character display
• Start address of the CG RAM table: 4800H
• Character code of defined pattern: 80H (first character code in CG RAM area)
([FX] 8 dots)” on page 45.
