46.3 Power Consumption
Typical power consumption of PLLs, Slow Clock and Main Oscillator.
Power consumption of power supply in four different modes: Active, Idle, Ultra Low-power and Backup.
Power consumption by peripheral: calculated as the difference in current measurement after having enabled then
disabled the corresponding clock.
