The digital processing circuit includes a plurality of bus masters coupled to a shared bus. A bus arbiter is provided for arbitrating between requests to access the bus by a first bus master and one or more other bus masters. Accesses by the one or more other bus masters to the bus are restricted in response to a signal indicative of a change in a mode of operation of the RF circuit. In one particular implementation, a communication apparatus employs time domain isolation wherein the digital processing circuit may be placed in a shutdown mode when the radio frequency circuit is active."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication apparatus implementing time domain isolation with restricted bus access","description":"A communication apparatus includes a radio frequency circuit that operates on a radio frequency signal and a digital processing circuit coupled to the radio frequency circuit.
