Abstract
Systems and methods are disclosed that replace a separate reset pin in a bus with a reset command that guarantees a system recovery. The system comprises a host component circuitry residing on a first chip and a client component circuitry residing on a second, different chip. A bus connects the host component circuitry to the client component circuitry. The host component circuitry is configured to transfer an initial client value associated with a client component time period to the client component circuitry over the bus on a periodic time basis. The periodic time basis is dictated by a host component time period and the client component time period is greater than the host component time period. The client component circuitry is configured to initiate a reset procedure if the client component time period expires which indicates that the initial client value was not received at a next time on the periodic time basis dictated by the host component time period.
