发明名称 Configuring power domains of a microcontroller system
摘要 A microcontroller system is organized into power domains. A power manager of the microcontroller system can change the power configuration of a power domain in response to event from an event generating module without activating a processor of the microcontroller system.

主权项 1. A microcontroller system comprising: a processor; a power manager coupled to the processor; and an event generating module coupled to the power manager; wherein the microcontroller system is organized into a plurality of power domains, including a first power domain including the processor and a second power domain different from the first power domain, the event generating module being in a different power domain from the processor and the second power domain, the power manager being in a different power domain from the processor, the event generating module, and the second power domain; and wherein the power manager is configured to perform operations comprising: powering down the first power domain so that the processor is inactive;receiving an event from the event generating module, the event being associated with the event generating module and independent of a power state of the processor; andin response to receiving the event from the event generating module and prior to activating the processor, changing the second power domain from a prior power configuration to a new power configuration, independent of the power state of the processor.
