Abstract
An integrated circuit device includes a peripheral control circuit configured to receive a low power intent signal from a first processor, and a first control register in the peripheral control circuit. The first control register includes a peripheral enable indicator for each processor that can use a first peripheral. Acknowledgement logic circuitry is configured to assert a first low power acknowledgement signal when the first processor issuing the low power intent signal has enabled use of the first peripheral as indicated by the peripheral enable indicator for the first processor in the first control register.
