3.14 Compact PCI Hot-Swap Support

The PCI2050 is hot-swap friendly silicon that supports all of the hot-swap capable features, contains support for

software control, and integrates circuitry required by the

CPCI Hot-Swap Specification. To be hot-swap capable, the

PCI2050 supports the following:

•

Compliance with

PCI Local Bus Specification

•

Tolerance of VCC from early power

•

Asynchronous reset

•

Tolerance of precharge voltage

•

I/O buffers must meet modified V/I requirements

•

Limited I/O pin voltage at precharge voltage

•

Hot-swap control and status programming via extended PCI capabilities linked list

•

Hot-swap terminals: HS_ENUM, HS_SWITCH, and HS_LED

CPCI hot-swap defines a process for installing and removing PCI boards without adversely affecting a running

system. The PCI2050 provides this functionality such that it can be implemented on a board that can be removed

and inserted in a hot-swap system.

The PCI2050 provides three terminals to support hot-swap when configured to be in hot-swap mode: HS_ENUM

(output), HS_SWITCH (input), and HS_LED (output). The HS_ENUM output indicates to the system that an insertion

event occurred or that a removal event is about to occur. The HS_SWITCH input indicates the state of a board ejector

handle, and the HS_LED output lights a blue LED to signal insertion and removal ready status.
