I/O Card Interface Timing: Figures 13.54 and 13.55 show the timing for the PCMCIA I/O card
interface.
When an I/O card interface access is made to a PCMCIA card in little-endian mode, dynamic
sizing of the I/O bus width is possible using the IOIS16 pin. When a 16-bit bus width is set, if the
IOIS16 signal is high during a word-size I/O bus cycle, the I/O port is recognized as being 8 bits
in width. In this case, a data access for only 8 bits is performed in the I/O bus cycle being
executed, followed automatically by a data access for the remaining 8 bits. Dynamic bus sizing is
also performed in the case of byte-size access to address 2n + 1.
Figure 13.56 shows the basic timing for dynamic bus sizing.
