Card Status Interrupt Configuration Register Description
Bits
Description
Bit 3
Bit 2
Bit 1
Bit 0
Card Detect Enable. When set to "1", this bit enables an interrupt by CD1 and CD2 status change.
When set to "0", this bit disables an interrupt by CD1 and CD2 status change common to both memory
and I/O mode.
Battery Warning Enable. In the memory mode, when set to "1", this bit enables an interrupt to Battery
Warning State(GoodWarning, DeadWarning). When set to "0", this bit disables an interrupt to Battery
Warning State (GoodWarning, DeadWarning).
Ready Enable. In the memory mode, when set to "1", this bit enables an interrupt to RDY/
BSY (LH).
When set to "0", this bit disables an interrupt to RDY/
BSY (LH).
Battery Dead Enable. In the memory mode, when set to "1", this bit enables an interrupt to Battery
Dead State (GoodDead, WarningDead) and also enables an interrupt to the
STSCHG Signal
Status Change in I/O card mode. When set to "0", this bit disables Battery State interrupt
STSCHG
change interrupt.
