PRELIMINARY

MB95610H Series

12. Memory Space

The memory space of the MB95610H 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 MB95F614H/F614K/F616H/F616K, the area from 0x0090 to 0x047F is an extended direct addressing area. It can be accessed

at high-speed by direct addressing instructions with a direct bank pointer set.

❐ In MB95F613H/F613K, 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.
