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+ is included. The WDT+ is clocked by SMCLK.
4. Current for Brownout and WDT+ is included. The WDT+ is clocked by ACLK.
