7.1. About power management

The processor extensively uses gated clocks to disable unused functionality, and disables inputs to unused functional blocks, so that only actively used logic consumes any dynamic power.

The ARMv7-M architecture supports system sleep modes that can stop the Cortex-M3 and system clocks for greater power reductions. These are described in System power management.
