1. Current consumption from the V
DDA
supply is independent of whether the peripherals are on or off. Furthermore when the
PLL is off, I
DDA
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.
