Table 3-2: PR31500/PR31700 to PC Card Slots Address Remapping Using the IT8368E
Table 3-1: PR31500/PR31700 to Unbuffered PC Card Slots System Address Mapping
Note
When the PR31500/PR31700 accesses the PC Card slots without the ITE IT8368E, its system
memory is mapped as in Table 3-1:, “PR31500/PR31700 to Unbuffered PC Card Slots System
Address Mapping”.
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 SED1374 access. Table 3-2:, “PR31500/PR31700 to PC Card Slots
Address Remapping Using the IT8368E” provides all details of the Attribute/IO address reallocation
by the IT8368E.
Bits CARD1IOEN and CARD2IOEN need to be set in PR31500/PR31700 Memory
