35.3 Power Consumption
• Power consumption of the device according to the different Low Power Mode Capabilities
(Backup, Wait, Sleep) and Active Mode.
• Power consumption on power supply in different modes: Backup, Wait, Sleep and Active.
• Power consumption by peripheral: calculated as the difference in current measurement after
having enabled then disabled the corresponding clock.
