PEX8624-SIL-PB-P1-0.8
Software Usage Model
From a system model viewpoint, each PCI Express port
is a virtual PCI to PCI bridge device and has its own set
of PCI Express configuration registers. It is through the
upstream port that the BIOS or host can configure the
other ports using standard PCI enumeration. The virtual
PCI to PCI bridges within the PEX 8624 are compliant
to the PCI and PCI Express system models. The
Configuration Space Registers (CSRs) in a virtual
primary/secondary PCI to PCI bridge are accessible by
type 0 configuration cycles through the virtual primary
bus interface (matching bus number, device number, and
function number).
Interrupt Sources/Events
The PEX 8624 switch supports the INTx interrupt
message type (compatible with PCI 2.3 Interrupt signals)
or Message Signaled Interrupts (MSI) when enabled.
Interrupts/messages are generated by PEX 8624 for hot
plug events, doorbell interrupts, baseline error reporting,
and advanced error reporting.
