4.4.2 Wait Mode

The purpose of Wait mode is to achieve low power consumption while maintaining the whole device in a powered state for a start-up time of a few μs. For current consumption in Wait mode, refer to the section Electrical Characteristics.

In this mode, all clocks are stopped when Wait mode is entered. However, the power supplies of digital logic and memories are maintained using Standby mode of the core voltage regulator to ensure memory and CPU context retention.

The device can handle external and internal events in order to perform a wake-up. This is done by configuring one or several internal or external wake-up sources.
