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.
