4.1 Low-Power Modes

Low-power modes are device states where minimum components are turned on and the device is waiting for an interrupt to wake up back to normal operation. The goal of low-power modes are to minimize power consumption and improve energy efficiency when the device is standing idle. For more details of the various low-power modes, wake up sources, and sleep sequencing, see the Power Modes section of the AM62x Technical Reference Manual. Note that not all the features described in the device-specific Technical Reference Manual have been implemented into the Software Development Kit.
