|
Always On Processor/Resource Power Manager maintains statistics of the SoC
|
|
sleep modes involving powering down of the rails and oscillator clock.
|
|
|
|
Statistics includes SoC sleep mode type, number of times low power mode were
|
|
entered, time of last entry, time of last exit and accumulated sleep duration.
