2. HSI oscillator is OFF for this measure.
3. These values correspond to the Flash memory dynamic current consumption. The Flash memory static
consumption (Flash memory ON) equals 12 µA and does not depend on the frequency.
The Flash memory consumption is already taken into account in all the supply current consumption tables
(Flash memory ON cases).
