The RF5C296 provides I/O address mapping as shown in the figure below :
In the above figure, addresses “03E0h” and “03E1h” form an internal address space for use in internal decoding.
On the other hand, the RF5C396 is capable of I/O address mapping in such a manner as to ensure I/O address
mismatching between the ISA bus and the PC card bus.
The above-described settings of the I/O Address n Start/Stop Low/High Byte Registers for the RF5C296 can be
added to the settings of the Card I/O Offset Address n Low/High Byte Registers (Index : 36h (Low-byte Window 0),
37h (High-byte Window 0), 38h (Low-byte Window 1), and 39h (High-byte Window 1)) to form two's complement
numbers representing I/O addresses on the PC card bus.
The Card I/O Offset Address n Low/High Byte Registers, which always default to “00h”, may be omitted from
setting to ensure I/O address matching between the ISA bus and the PC card bus in the same manner as for the
RF5C296.
