Card Detect Change.
0: No change detected on either CD2# or CD1#.
1: A change has been detected on CD2# and CD1#.
Ready Change.
0: No change on RDY/BSY#, or I/O PC Card installed.
1: When a low to high has been detected on the RDY/BSY# signal indicating that the memory PC
Card is ready to accept a new data transfer.
Battery Warning.
0: No battery warning condition, or I/O PC Card installed.
1: A battery warning condition has been detected.
Battery Dead ( STSCHG# )
For memory PC Cards, bit is set one when a battery dead condition has been detected.
For I/O PC Cards, bit is set to one if ring indicate enable bit in the interrupt and general control
register is set to zero and the STSCHG/RI# signal from the I/O PC Card has been pulled low. The
system software then has to read the status change register in the PC Card to determine the cause of
the status change signal STSCHG#. This bit reads zero for I/O PC Cards if the ring indicate enable
bit in the interrupt and general control register is set to one.

NOTE :
The Card Status Change Register contains the status for sources of the card status change
interrupt. These sources can be enabled to generate a card status change interrupt by setting the
corresponding bit in the card status change interrupt configuration register. Reading the Card
Status Change Register causes the register bits to be reset to zero.
If the card status change interrupt is enabled to one of the system bus interrupt request lines,
the corresponding IRQ signal remains active high until this register is read.
