Notes:
1. Currents are additive. For example, where I_DD is specified and the mode is not mutually exclusive, enabling the
functions increases supply current by the specified amount.
2. Includes supply current from internal regulator, supply monitor, and High Frequency Oscillator
3. Includes supply current from internal regulator, supply monitor, and Low Frequency Oscillator
4. ADC0 always-on power excludes internal reference supply current
5. The internal reference is enabled as-needed when operating the ADC in burst mode to save power.
