Figure 9.39 Wait Timing for PCMCIA Memory Card Interface
(TED[3:0] = B'0010, TEH[3:0] = B'0001, Hardware Wait = 1)
When 32 Mbytes of the memory space are used as IC memory card interface, a port is used to
generate the REG signal that switches between the common memory and attribute memory. When
the memory space used for the IC memory card interface is 16 Mbytes or less, pin A24 can be
used as the REG signal by allocating a 16-Mbyte common memory space and a 16-Mbyte attribute
memory space.
