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.
46.3.1 Power Consumption versus Modes
The values in Table 46-3 and Table 46-4 are estimated values of the power consumption with operating conditions as
follows:
 V
