Abstract

The described techniques address deadlocking issues associated with interconnected hardware devices that share bus lines associated with a digital communication interface. A watchdog-based solution is described that may be implemented internally within the interconnected hardware devices or, alternatively, as an external component. The watchdog circuity may monitor a logic state of one or more internal connections of a hardware device and cause one or more portions of the hardware device to reset when a deadlock condition is detected using this internal monitoring.
