Power Consumption
Power consumption of the device according to the different Low Power mode capabilities (backup, wait, sleep) and
active mode.
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.
