Figure 314. IRQ Implementation
Power-on software is responsible for programming the multifunction routing register to reflect the IRQ configuration
of a system implementing the controller. See Section 4.30,
Multifunction Routing Register
,
for details on configuring
the multifunction terminals.
The parallel ISA-type IRQ signaling from the MFUNC6MFUNC0 terminals is compatible with the input signal
requirements of the 8259 PIC. The parallel IRQ option is provided for system designs that require legacy ISA IRQs.
Design constraints may demand more MFUNC6MFUNC0 IRQ terminals than the controller makes available.
3.7.4
Using Parallel PCI Interrupts
Parallel PCI interrupts are available when exclusively in parallel PCI interrupt/parallel ISA IRQ signaling mode, and
when only IRQs are serialized with the IRQSER protocol. Socket functional interrupts can be routed to INTA.
3.7.5
Using Serialized IRQSER Interrupts
The serialized interrupt protocol implemented in the controller uses a single terminal to communicate all interrupt
status information to the host controller. The protocol defines a serial packet consisting of a start cycle, multiple
interrupt indication cycles, and a stop cycle. All data in the packet is synchronous with the PCI clock. The packet data
describes 16 parallel ISA IRQ signals and the optional 4 PCI interrupts INTA, INTB, INTC, and INTD. For details on
the IRQSER protocol, refer to the document
Serialized IRQ Support for PCI Systems
.
3.7.6
SMI Support in the PCI1510 Controller
The controller provides a mechanism for interrupting the system when power changes have been made to the PC
Card socket interfaces. The interrupt mechanism is designed to fit into a system maintenance interrupt (SMI) scheme.
SMI interrupts are generated by the controller, when enabled, after a write cycle to either the socket control register
(CB offset 10h, see Section 6.5) of the CardBus register set, or the ExCA power control register (ExCA offset
02h/42h/802h, see Section 5.3) causes a power cycle change sequence to be sent on the power switch interface.
The SMI control is programmed through three bits in the system control register (PCI offset 80h, see Section 4.29).
These bits are SMIROUTE (bit 26), SMISTATUS (bit 25), and SMIENB (bit 24). Table 39 describes the SMI control
bits function.
Table 39. SMI Control
BIT NAME
FUNCTION
SMIROUTE
This shared bit controls whether the SMI interrupts are sent as a CSC interrupt or as IRQ2.
SMISTAT
This socket dependent bit is set when an SMI interrupt is pending. This status flag is cleared by writing back 1b.
SMIENB
When set, SMI interrupt generation is enabled.
If CSC SMI interrupts are selected, then the SMI interrupt is sent as the CSC on a per-socket basis. The CSC interrupt
can be either level or edge mode, depending upon the CSCMODE bit in the ExCA global control register (ExCA offset
1Eh/5Eh/81Eh, see Section 5.20).
If IRQ2 is selected by SMIROUTE, then the IRQSER signaling protocol supports SMI signaling in the IRQ2 IRQ/Data
slot. In a parallel ISA IRQ system, the support for an active low IRQ2 is provided only if IRQ2 is routed to either
MFUNC3 or MFUNC6 through the multifunction routing register (PCI offset 8Ch, see Section 4.30).
