SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
(2) SYRAM
You can set characters for 7 letters per screen (SYRAM code
0016 to 0616). Figure 9 shows an example of how to set.
Use display RAM’s SYC2 to 0 (0016 to 0616) to specify SYRAM.
Note that SYRAM code 0716 is fixed to a blank, so you cannot set
a character font to this code.
If you do not put SYRAM and a character together, use code
0716.
(ex) SYRAM code 0016 .................. Set character by setting data to address 30016 to 30C16
