57.3.1 Backup Mode Current Consumption and Wakeup Time

The Backup mode configurations and measurements are defined as follows:

Embedded slow clock RC oscillator is enabled
Supply Monitor on V_DDIO is disabled
RTC is running
RTT is enabled on 1 Hz mode
BOD is disabled
One WKUPx enabled
Current measurement on AMP1 with and without the 1 Kbyte backup SRAM
Measurements are made at ambient temperature
