1. Current consumption from the VDDA supply is independent of whether the digital peripherals are enabled or disabled, being

in Run or Sleep mode or executing from Flash memory or RAM. Furthermore, when the PLL is off, IDDA is independent from

the frequency.

2. Data based on characterization results, not tested in production unless otherwise specified.

3. Data based on characterization results and tested in production (using one common test limit for sum of IDD and IDDA).
