Abstract
Private devices are implemented on the secondary interface of PCI bridge by re-routing the activation of device select signals (IDSEL) during the address phase of a Type 0 configuration operation on the secondary bus in response to a Type 1 configuration operation on its primary bus. Under control of a mask register and device select reroute circuit, if a configuration command on the primary interface attempts to activate the IDSEL line associated with one of the private, or reroute, devices on the secondary interface, a different IDSEL is activated to select a monitoring device on the secondary interface.
