Figures 8.46 and 8.47 show the basic timings for the PCMCIA I/O card interface.
When accessing an I/O card with the PCMCIA interface, be sure to access the cache-disabled
spaces.
The I/O card and IC memory card interfaces are switched by an address to be accessed according
to the SA[1:0] bit settings in CS5WCR and CS6WCR.
Note that the bus width cannot be switched dynamically with the IOIS16 signal, which is output
from an I/O card. The bus width must always be switched by modifying the CS5BCR or CS6BCR
setting. In addition, there are some restrictions on the bus width of the I/O card interface. For
details, see section 8.6, Usage Notes.
