MEMORY MAP
The MB90230 series can access the 00 bank to read ROM data written to the upper 48-KB locations in the FF
bank. An advantage of reading written to data addresses FFFFFF

from addresses 00FFFF
H
-004000

is
that you can use the small model of a C compiler.
Note, however, that the products with more than 48KB ROM space (MB90V230, MB90P/W234, MB90234) cannot
read data in addresses other than FFFFFF
H
to FF4000
