NOTES: 1. All inputs are tied to 0 V or V
CC
. 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 9 pF.
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.
