Figures 11.18 and 11.19 show the timing for the PCMCIA I/O card interface.
When accessing a PCMCIA card via the I/O card interface, it is possible to perform dynamic
sizing of the I/O bus width using the IOIS16 pin. With the 16-bit bus width selected, if the IOIS16
signal is high during the word-size I/O bus cycle, the I/O port is recognized as eight bits in bus
width. In this case, a data access for only eight bits is performed in the I/O bus cycle being
executed, and this is automatically followed by a data access for the remaining eight bits. Dynamic
bus sizing is also performed for byte-size access to address 2n + 1.
Figure 11.20 shows the basic timing for dynamic bus sizing.
