45.3 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
45.3.1 Backup Mode Current Consumption
The Backup mode configuration and measurements are defined as follows.
45.3.1.1 Backup Power Configuration
 All power supplies OFF, except VDDBU
 Supply Monitor on VDDUTMI is disabled
 RTT and RTC not used
 Embedded RC oscillator used
 Wake-up pin FWUP = VDDBU
 Current measurement on AMP1
