Abstract
A system and method for automatically assigning resources to a slave device inserted into a PCI backplane utilizes pairs of PCI GNT/REQ lines as bus lines of a time division multiplexed multiplexer control bus. The slave device generates a random delay number and utilizes the number to select an unassigned time slot to be assigned to the slave device. Configuration data is transferred to the slave utilizing the already existing PCI GNT/REQ lines so that no additional bus lines and card space are required to automatically assign resources to the slave device.
