Figure 7.33 Example of PCMCIA Space Assignment (CS5BWCR.SA[1:0] = B'10,

CS6BWCR.SA[1:0] = B'10)

Basic Timing for I/O Card Interface: Figures 7.34 and 7.35 show the basic timings for the

PCMCIA I/O card interface.

The I/O card and IC memory card interfaces are specified by an address to be accessed. When

area 5 of the physical space is specified as the PCMCIA and both bits SA1 and SA0 in CS5BWCR

are set to 1, the I/O card interface can automatically be specified by accessing the physical

addresses from H'16000000 to H'17FFFFFF and from H'14000000 to H'15FFFFFF. When area 6

of the physical space is specified as the PCMCIA and both bits SA1 and SA0 in CS6BWCR are

set to 1, the I/O card interface can automatically be specified by accessing the physical addresses

from H'1A000000 to H'1BFFFFFF and from H'18000000 to H'19FFFFFF.

Note that areas to be accessed as the PCMCIA I/O card must be non-cached (space P2).

If the PCMCIA card is accessed as an I/O card in little endian mode, dynamic bus sizing for the

I/O bus can be achieved using the

IOIS16 signal. If the IOIS16 signal is driven high in a word-size

I/O bus cycle while the bus width of area 6 is specified as 16 bits, the bus width is recognized as 8

bits and data is accessed twice in units of eight bits in the I/O bus cycle to be executed.
