Card Interrupt Status Enable
If this bit is set to 0, the Host Controller shall clear 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
should clear the
Card Interrupt Status Enable
before servicing the
Card Interrupt
and should set this bit again after all interrupt
requests from the card are cleared to prevent inadvertent interrupts.
