14.2 Overview

The Power Manager (PM) manages the device’s sleep modes.

Various sleep modes are available to meet different power consumption needs. In Active mode, the CPU runs the application code. When the device enters a sleep mode, program execution stops, and the PM automatically disables certain peripherals and clock domains depending on the sleep mode. The application code determines which sleep mode to enter and when. Interrupts from enabled peripherals or reset sources can wake the device from sleep mode and return it to Active mode.
