• Description: Renesas 32-Bit RISC Microcomputer SuperHTM RISC engine Family / SH7700 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

If all 32 Mbytes of the memory space are used as an IC memory card interface, the REG signal
that switches between the common memory and attribute memory can be generated by an I/O port.
If the memory space used for the IC memory card interface is 16 Mbytes or less, the A24 pin can
be used as the REG signal by using the memory space as a 16-Mbyte common memory space and
a 16-Mbyte attribute memory space.
