Abstract: Deselect times can be specified for transactions that are to utilize a communication bus shared by multiple devices. A host can communicate with a multiplexer to select a channel for communication on that bus. If this host communicates with the multiplexer over the bus as well, the host can be prevented from instructing the multiplexer to deselect a channel if the bus is hung. To provide for recovery in such situations, one or more deselect times can be specified for one or more channels of a bus. If a transaction for a device on one of these channels is ongoing when the deselect time is reached, the multiplexer can automatically deselect that channel in order to enable other devices to communicate over other channels on that bus. In some embodiments, a riskiness of a transaction or device can be determined for purposes of applying or determining a relevant deselect time.
