20.6.1.4 Power Domain States and Gating

In Standby sleep mode, the Power Domain Gating technique allows for selecting the state of a PDn power domain automatically (e.g. for executing sleepwalking tasks) or manually:

Active State

The power domain is powered according to the performance level

Retention State

The main voltage supply for the power domain is switched off, while maintaining a secondary low-power supply for sequential cells. The logic context is restored when waking up.

Off State

The power domain is entirely powered off. The logic context is lost.
