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 or RAM. Furthermore, when the PLL is off, I
DDA
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 I
DD
and I
DDA
).
