Card Interrupt Status Enable
If this bit is set to 0, the Host Controller clears interrupt request to the
System. The
Card Interrupt
detection is stopped when this bit is
cleared and restarted when this bit is set to 1. The Host Driver must
clear the
Card Interrupt Status Enable
before servicing the
Card
Interrupt
and must set this bit again after all interrupt requests from the
card are cleared to prevent inadvertent interrupts.
