NOTE:
1. Since the emulator between the M16C/26A Group and M16C/29 Group are the same, all functions of
M16C/29 are built in the emulator. When evaluating M16C/26A Group, do not access to the SFR which
is not built in M16C/26A Group. Refer to Hardware Manual about detail and electrical characteristics.
