1. Current consumption from the VDDA supply is independent of whether the peripherals are on or off. Furthermore when the

PLL is off, IDDA is independent from the frequency.

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

3. Data based characterization results and tested in production with code executing from RAM.
