NOTES:
1. All inputs are tied to 0 V or V_CC. Outputs do not source or sink any current.
2. For < 105_C, 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. For > 105_C, the currents are characterized using a
32 kHz external clock source for ACLK..
