Interfacing to the Toshiba MIPS TX3912 Processor
Issue Date: 01/02/08
The TX3912 uses a portion of the PC Card Attribute and IO space to access the S1D13506.
The S1D13506 responds to both PC Card Attribute and IO bus accesses, thus freeing the
programmer from having to set the TX3912 Memory Configuration Register 3 bit
CARD1IOEN (or CARD2IOEN if slot 2 is used). As a result, the TX3912 sees the
S1D13506 on its PC Card slot as described in the table below.
