23 / 41 page ![]() 22 MITSUBISHI MICROCOMPUTERS M35062-XXXSP 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. Fig. 9 Setting example of SYRAM (ex) SYRAM code 0016 ..................
