The processor can be awakened from an interrupt if WFI instruction of the Cortex M3 is used, or
from an event if the WFE instruction is used to enter this mode.

Low Power Mode Summary Table
The modes detailed above are the main low power modes. Each part can be set to on or off sep-
arately and wake-up sources can be individually configured. Table 5-1 below shows a summary
of the configurations of the low power modes.
Notes:
1. SUPC, 32 kHz Oscillator, RTC, RTT, Backup Registers, POR
2. The external loads on PIOs are not taken into account in the calculation.
3. BOD current consumption is not included.
4. When considering the wake-up time, the time required to start the PLL is not taken into account. Once started, the device
works with the 4/8/12 MHz Fast RC oscillator. The user has to add the PLL start-up time if it is needed in the system. The
wake-up time is defined as the time taken for wake-up until the first instruction is fetched
5. Current consumption on VDDBU.
6. 18.4 A on VDDCORE, 26.6 A for total current consumption (using internal voltage regulator).
7. Depends on MCK frequency. In this mode, the core is supplied and not clocked but some peripherals can be clocked.
