1. Typical values not tested in production. Since the peripherals are powered by an internally regulated,
constant digital supply voltage, the values are similar in the full supply voltage range.
2. Data based on a differential I_DD measurement between no peripheral clocked and a single active
peripheral. This measurement does not include the pad toggling consumption.
3. Data based on a differential I_DD measurement between reset configuration and continuous A/D
conversions.
