NOTES:

1. All inputs are tied to 0 V or VCC. Outputs do not source or sink any current.

2. The currents are characterized with a Micro Crystal CC4V−T1A SMD crystal with a load capacitance of 9 pF.

The internal and external load capacitance is chosen to closely match the required 9pF.

3. Current for brownout and WDT clocked by SMCLK included.

4. Current for brownout and WDT clocked by ACLK included.

5. Current for brownout included.
