Figure 10.44 Wait Timing for PCMCIA Memory Card Interface Burst Access
When the entire 32-Mbyte memory space is used as IC memory card interface space, the common
memory/attribute memory switching signal REG is generated using a port, etc. If 16-Mbytes or
less of memory space is sufficient, using 16M bytes of memory space as common memory space
and 16 Mbytes as attribute memory space enables the A24 pin to be used for the REG signal.
