7.6.3 Sleep Mode

The purpose of Sleep mode is to optimize power consumption of the device versus response time. In this mode, only the core clock is stopped. The peripheral clocks can be enabled. The current consumption in this mode is application-dependent.

This mode is entered using the instruction Wait for Interrupt (WFI).

Processor wakeup is triggered by an interrupt if the WFI instruction of the Cortex-M processor is used.
