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 T_a > 105°C, ACLK was sourced from
an external clock source.
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.
5. Current for Brownout included.
