Abstract
A controller ( ) for coupling between a computer bus ( ) and one or more units ( ) compatible with the bus. The controller comprises a first input ( ) for receiving a first reset signal issued from the computer bus, and a second input ( ) for receiving a second reset signal. The controller further comprises circuitry ( ) for storing a first set of information which will be cleared in response to assertion of the first reset signal. Lastly, the controller comprises circuitry ( ) for storing a second set of information which will not be cleared in response to assertion of the first reset signal but which will be cleared in response to assertion of the second reset signal. In a described embodiment, the bus is a PCI bus, the first reset signal is a PCI Reset signal, and the second reset signal is an initialization signal.
