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 included.
