(2) I/O Card Interface Timing
Figures 10.40 and 10.41 show the timing for the PCMCIA I/O card interface.
When accessing a PCMCIA card as an I/O card interface, it is possible to perform dynamic sizing
of the I/O bus width using the IOIS16 pin. With a 16-bit bus width selected, if the IOIS16 signal is
high during a word-size I/O bus cycle, the I/O port is recognized as 8 bits in width. In this case, a
data access for only 8 bits is performed in the I/O bus cycle being executed, and this is
automatically followed by a data access for the remaining 8 bits. Dynamic bus sizing is also
performed for byte-size access to address 2n + 1.
Figure 10.42 shows the basic timing for dynamic bus sizing.
