As described before, the settings of bit7 and bit6 (Slot bit) in the Index Register depend on the status of the
SPKROUT# pin for the RF5C396 or the RI_OUT# pin for the RF5C296 and on the status of the the SPKROUT# pin
for the RF5C296, respectively, at the falling edge of the RESETDRV pin signal. Therefore, 4 slots system can be con-
structed using plural RF5C296/RF5C396's without modifying I/O address (3E0h, 3E1h)
1-slot system : one RF5C296
2-slot system : one RF5C396 or two RF5C296
3-slot system : one RF5C396 and one RF5C296, or three RF5C296
4-slot system : two RF5C396, or one RF5C396 and two RF5C296, or four RF5C296
The following tables show the relation between the index range and the status of SPKROUT# and RI-OUT# when
RESETDRV falls.

More than five PC card slots can also be supported through external decoding of the A15 to A1 pin signals for
input to the CS# pin and thereby setting of any given I/O addresses of the internal registers for the RF5C296 and
the RF5C396.
Notice
Access to any other index range than is specified at power-on is invalidated while any attempt to read the Index
Register results in a data bus output of high impedance.
