14. Memory Space
The memory space of the MB95710M/770M Series is 64 Kbyte in size, and consists of an I/O area, an extended I/O
area, a data area, and a program area. The memory space includes areas for specific applications such as general-
purpose registers and a vector table.
• I/O area (addresses: 0x0000 to 0x007F)
• This area contains the control registers and data registers for built-in peripheral functions.
• As the I/O area forms part of the memory space, it can be accessed in the same way as the memory. It can also
be accessed at high-speed by using direct addressing instructions.
• Extended I/O area (addresses: 0x0F80 to 0x0FFF)
• This area contains the control registers and data registers for built-in peripheral functions.
• As the extended I/O area forms part of the memory space, it can be accessed in the same way as the memory.
• Data area
• Static RAM is incorporated in the data area as the internal data area.
• The internal RAM size varies according to product.
• The RAM area from 0x0090 to 0x00FF can be accessed at high-speed by using direct addressing instructions.
• In MB95F716J/F716M/F718J/F718M/F776J/F776M/F778J/F778M, the area from 0x0090 to 0x047F is an extend-
ed direct addressing area. It can be accessed at high-speed by direct addressing instructions with a direct bank
pointer set.
• In MB95F714J/F714M/F774J/F774M, the area from 0x0090 to 0x028F is an extended direct addressing area. It
can be accessed at high-speed by direct addressing instructions with a direct bank pointer set.
• The area from 0x0100 to 0x01FF can be used as a general-purpose register area.
• Program area
• The Flash memory is incorporated in the program area as the internal program area.
• The Flash memory size varies according to product.
• The area from 0xFFC0 to 0xFFFF is used as the vector table.
• The area from 0xFFBB to 0xFFBF is used to store data of the non-volatile register.
