Internal Clock Source (ICS) Characteristics
1 3 V values are 100% tested; 2 V values are characterized but not tested.
2 Typicals are measured at 25
°C.
3 Does not include any DC loads on port pins.
4 Most customers are expected to find that auto-wakeup from a stop mode can be used instead of the higher current wait mode.
