Abstract:
A component for a system having power management resources responsive to power management event signals to switch to an operating state; the component comprising:power logic having a first mode in which power consumption is limited to a first specified level, and a second mode in which power consumption is limited to a second specified level higher than the first specified level; an interface to nonvolatile memory storing a control signal; logic, coupled to the interface to nonvolatile memory and responsive to detection of a power supply voltage, to read in the first mode the control signal from the nonvolatile memory, and to signal the power logic to enter the second mode in response to a specified state of the control signal; and monitoring resources operating in the second mode which monitor for an event, and in response to detection of the event, produce a signal to cause the system to switch to the operating mode.
