Notes on Using Evaluation Products
The Evaluation product has not only the functions of the MB95120MB series but also those of other products
to support software development for multiple series and models of the F
2
MC-8FX family. The I/O addresses for
peripheral resources not used by the MB95120MB series are therefore access-barred. Read/write access to
these access-barred addresses may cause peripheral resources supposed to be unused to operate, resulting
in unexpected malfunctions of hardware or software.
Particularly, do not use word access to odd numbered byte address in the prohibited areas (If these access are
used, the address may be read or written unexpectedly).
Also, as the read values of prohibited addresses on the evaluation product are different to the values on the
Flash memory and MASK ROM products, do not use these values in the program.
The Evaluation product do not support the functions of some bits in single-byte registers. Read/write access to
these bits does not cause hardware malfunctions. Since the Evaluation, Flash memory product, and MASK ROM
product are designed to behave completely the same way in terms of hardware and software.
•
Difference of Memory Spaces
If the amount of memory on the Evaluation product is different from that of the Flash memory product or MASK
ROM product, carefully check the difference in the amount of memory from the model to be actually used when
developing software.
For details of memory space, refer to “■ CPU CORE”.
•
Current Consumption
• The current consumption of Flash memory product is typically greater than for MASK ROM product.
• For details of current consumption, refer to “■ ELECTRICAL CHARACTERISTICS”.
