Figure 11.39 Wait Timing for PCMCIA Memory Card Interface
(TED[3:0] = B'0010, TEH[3:0] = B'0001, Software Wait = 1, Hardware Wait = 1)
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 a 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.
