Programmable Interrupt Subsystem
Interrupts provide a way for I/O devices to let the microprocessor know that they require servicing. The dynamic
nature of PC Cards and the abundance of PC Card I/O applications require substantial interrupt support from the
PCI6515 controller. The PCI6515 controller provides several interrupt signaling schemes to accommodate the needs
of a variety of platforms. The different mechanisms for dealing with interrupts in this controller are based on various
specifications and industry standards. The ExCA register set provides interrupt control for some 16-bit PC Card
functions, and the CardBus socket register set provides interrupt control for the CardBus PC Card functions. The
PCI6515 controller is, therefore, backward compatible with existing interrupt control register definitions, and new
registers have been defined where required.
The PCI6515 controller 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 PCI6515 controller,
PC Card interrupts are classified either as card status change (CSC) or as functional interrupts.
The method by which any type of PCI6515 interrupt is communicated to the host interrupt controller varies from
system to system. The PCI6515 controller 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, MFUNC0MFUNC6.
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
PCI6515 controller and may warrant notification of host card and socket services software for service. CSC events
include both card insertion and removal from the PC Card socket, as well as transitions of certain PC Card signals.
