Claim 16:
17. A method comprising:
determining, by a circuit subsystem that is in an inoperable state, that a wake-up trigger event has occurred, the wake-up trigger event comprising an event related to the circuit subsystem;
responsive to determining that the wake-up trigger event has occurred, transmitting, by the circuit subsystem, over a link that is in a quiescent state, and to an interconnect that couples the circuit subsystem to one or more other circuit subsystems, a wake-up request signal;
detecting, by the interconnect and over the link, the wake-up request signal;
responsive to detecting the wake-up request signal, transmitting, by the interconnect and to a system processor in an awake state, the wake-up request signal to enable the system processor to communicate commands associated with a subsystem wake-up sequence; and
responsive to the interconnect transmitting the wake-up request signal to the system processor, sending, by the system processor, a command over the interconnect to the circuit subsystem to initiate the subsystem wake-up sequence to direct the circuit subsystem to exit the inoperable state.
