: Card Detect Enable. Setting bit to “1” enables a card status change interrupt when a change has been
detected on CD1# or CD2# signals.
: Ready Enable. Setting this bit to “1” enables a card status change interrupt when a “L” to “H” transition
has been detected on READY/BUSY# signals. This bit is ignored when interface is configured for I/O
card.
: Battery Warning Enable. Setting this bit to “1” enables a card status change interrupt when battery
warning condition has been detected. This bit is ignored when interface is configured for I/O card.
: Battery Dead Enable. For memory cards, Setting this bit to “1” enables a card status change interrupt
when a battery dead condition has been detected. For I/O cards, a card status change interrupt will be
generated if the STSCHG#/RI# has been pulled “L” assuming Ring Indicate Enable Bit (bit7) in
Interrupt and General Control Register is set to “0”.
