The PCI4410A device detects PC Card interrupts and events at the PC Card interface and notifies the host controller,
using one of several interrupt signaling protocols. To simplify the discussion of interrupts in the PCI4410A device, PC
Card interrupts are classified as either card status change (CSC) or as functional interrupts.
The method by which any type of PCI4410A interrupt is communicated to the host interrupt controller varies from
system to system. The PCI4410A device offers system designers the choice of using parallel PCI interrupt signaling,
parallel ISA-type IRQ interrupt signaling, or the IRQSER serialized ISA and/or PCI interrupt protocol. It is possible
to use the parallel PCI interrupts in combination with either parallel IRQs or serialized IRQs, as detailed in the sections
that follow. All interrupt signaling is provided through the seven multifunction terminals, MFUNC0

MFUNC6. In
addition, PCI interrupts (INTA and INTB) are available on dedicated pins.
3.7.1
PC Card Functional and Card Status Change Interrupts
PC Card functional interrupts are defined as requests from a PC Card application for interrupt service and are
indicated by asserting specially defined signals on the PC Card interface. Functional interrupts are generated by
16-bit I/O PC Cards and by CardBus PC Cards.
Card status change (CSC)-type interrupts are defined as events at the PC Card interface that are detected by the
PCI4410A device, and may warrant notification of host card and socket services software for service. CSC events
include both card insertion and removal from PC Card sockets, as well as transitions of certain PC Card signals.
Table 3
–
8 summarizes the sources of PC Card interrupts and the type of card associated with them. CSC and
functional interrupt sources are dependent on the type of card inserted in the PC Card socket. The three types of cards
that can be inserted into any PC Card socket are:
16-bit memory card
16-bit I/O card
CardBus cards

Functional interrupt events are valid only for 16-bit I/O and CardBus cards; that is, the functional interrupts are not
valid for 16-bit memory cards. Furthermore, card insertion and removal-type CSC interrupts are independent of the
card type. Table 3
–
9 describes the PC Card interrupt events.
