1. Current consumption from the V
DDA
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, I
DDA
is independent of
clock frequencies.

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