10.3.2. CG RAM addressing example
Define a pattern for the “A” in Figure 26.
The CG RAM table start address is 4800H.
The character code for the defined pattern is 80H (the
first character code in the CG RAM area).
As the character code table in Figure 46 shows, codes
80H to 9FH and E0H to FFH are allocated to the CG RAM
and can be used as desired. 80H is thus the first code for
CG RAM. As characters cannot be used if only using
graphics mode, there is no need to set the CG RAM data.
