¡ ´Set HD6801 to mode 5. P10 to P14 are used as the output port and P30 to P37 as the data bus.
¡ ´74LS154 4-to-16 decoder generates chip select signal to make specified AX6108 active after
decoding 4 bits of P10 to P13.
¡ ´Therefore, after enabling the operation by P10 to P13 and specifying D/I signal by P14, read/write
from/to the external memory area ($0100 to $01FE) to control AX6108. In this case, IOS signal is
output from SC1 and R/W signal from SC2.
¡ ´For details of HD6800 and HD6801, refer to their manuals.
