Notes: 1. Section 4 Design Considerations describes how to calculate the external supply current.

2. In order to obtain these results all inputs must be terminated (i.e., not allowed to float).

3. Values are given for PLL enabled.

4. Values are given for CKOUT enabled.

5. Periodically sampled and not 100% tested
