13. Areas for Specific Applications

The general-purpose register area and vector table area are used for the specific applications.

■ General-purpose register area (Addresses: 0x0100 to 0x01FF*)

❐ This area contains the auxiliary registers used for 8-bit arithmetic operations, transfer, etc.

❐ As this area forms part of the RAM area, it can also be used as conventional RAM.

❐ When the area is used as general-purpose registers, general-purpose register addressing enables high-speed access with short

instructions.

■ Non-volatile register data area (Addresses: 0xFFBB to 0xFFBF)

❐ The area from 0xFFBB to 0xFFBF is used to store data of the non-volatile register. For details, refer to “CHAPTER 27 NON-VOL-

ATILE REGISTER (NVR) INTERFACE” in “New 8FX MB95610H Series Hardware Manual”.

■ Vector table area (Addresses: 0xFFC0 to 0xFFFF)

❐ This area is used as the vector table for vector call instructions (CALLV), interrupts, and resets.

❐ The top of the Flash memory area is allocated to the vector table area. The start address of a service routine is set to an address

in the vector table in the form of data.

“

■ Interrupt Source Table” lists the vector table addresses corresponding to vector call instructions, interrupts, and resets.

For details, refer to “CHAPTER 4 RESET”, “CHAPTER 5 INTERRUPTS”, and “A.2 Special Instruction

■ Special Instruction ● CALLV

#vct” in “APPENDIX” in “New 8FX MB95610H Series Hardware Manual”.

■ Direct bank pointer and access area

*: Due to the memory size limit, the available access area is up to “0x028F” in MB95F613H/F613K.
