Interfacing to the Philips MIPS PR31500/PR31700 Processor
Issue Date: 01/02/05
The PR31500/PR31700 uses a portion of the PC Card Attribute and IO space to access the
S1D13505. The S1D13505 responds to both PC Card Attribute and IO bus accesses, thus
freeing the programmer from having to set the PR31500/PR31700 Memory Configuration
Register 3 bit CARD1IOEN (or CARD2IOEN if slot 2 is used). As a result, the
PR31500/PR31700 sees the S1D13505 on its PC Card slot as described in the table below.
