5 System Design Using the IT8368E PC Card Buffer
In a system design using one or two ITE IT8368E PC Card and multiple-function IO
buffers, the S1D13505 can be interfaced so as to share one of the PC Card slots.

5.1 Hardware Description

The IT8368E can be programmed to allocate the same portion of the PC Card Attribute and
IO space to the S1D13505 as in the direct connection implementation described in Section
4, Direct Connection to the Philips PR31500/PR31700 on page 11.
Following is a block diagram showing an implementation using the IT8368E PC Card
buffer.
