(1) All inputs are tied to 0 V or V_CC. Outputs do not source or sink any current.
(2) For T_A < 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 T_A > 105°C, the currents are characterized
using a 32-kHz external clock source for ACLK..
