Power Domain States and Gating

In Standby sleep mode, the Power Domain Gating technique allows for selecting the state of PDSW 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.
