Note
Note
The IT8368E provides eleven multi-function IO pins (MFIO). The IT8368E must have
both “Fix Attribute/IO” and “VGA” modes on. When both these modes are enabled, the
MFIO pins provide control signals needed by the S1D13705 host bus interface, and a 16M
byte portion of the system PC Card attribute and IO space is allocated to address the
S1D13705. When accessing the S1D13705 the associated card-side signals are disabled in
order to avoid any conflicts.
For mapping details, refer to section 3.3: “Memory Mapping and Aliasing.” For connection
details see Figure 5-1:

Buffer Chip Specification.
When the PR31500/PR31700 accesses the PC Card slots without the ITE IT8368E, its
system memory is mapped as in Table 5-1:
Mapping With and Without the IT8368E
When the PR31500/PR31700 accesses the PC Card slots buffered through the ITE
IT8368E, bits CARD1IOEN and CARD2IOEN are ignored and the attribute/IO space of
the PR31500/PR31700 is divided into Attribute, I/O and S1D13705 access. Table 5-1:
PR31500/PR31700 to PC Card Slots Address Mapping With and Without the IT8368E
provides all details of the Attribute/IO address reallocation by the IT8368E.
Size
When a second IT8368E is used, that circuit should not be set in VGA mode.
Bit CARD1IOEN or CARD2IOEN, depending on which card slot is used, must to be set
to 0 in the PR31500/PR31700 Memory Configuration Register 3.
