3.3 PCI Interrupts

The multifunction pin 0 of the PC Card socket controller is used as the PCI interrupt INTA#. The
PCI1520 provides a card status change interrupt which can notify the system of change in the PC
Card battery voltage levels, PC Card insertion / removal detection, Ready/Busy# condition and
functional status change for both sockets. These various interrupt sources of both PC Cards are
individually programmable to INTA# via ExCA “Card Status Change Interrupt Configuration Register”
at ExCA register offset 0x05.
