Note:

1. Currents are additive. For example, where IDD is specified and the mode is not mutually exclusive, enabling the functions increa-

ses supply current by the specified amount.

2. Includes supply current from regulators, supply monitor, and High Frequency Oscillator.

3. Includes supply current from regulators, supply monitor, and Low Frequency Oscillator.
