1. When considering wake-up time, the time required to start the PLL is not taken into account. Once started, the device works
2. The external loads on PIOs are not taken into account in the calculation.
3. Supply Monitor current consumption is not included.
4. Total Current consumption.
5. 5 µA on VDDCORE, 15 µA for total current consumption (using internal voltage regulator), 8 µA for total current consumption
6. Depends on MCK frequency.
7. In this mode the core is supplied and not clocked but some peripherals can be clocked.
