34.6 Application Information
34.6.1 STANDBY Mode Considerations
STANDBY offers maximum power saving possibility. But power is only saved during the time a power
domain is disconnected from the supply. Increased power is required when a power domain is re-connected
to the power supply. Additional power is required during restoring the information (e.g., in the platform).
Care should be taken that the time during which the SoC is operating in STANDBY mode is significantly
longer than the required time for restoring the information.
