1. Guaranteed based on test during characterization, unless otherwise specified.

2. Based on characterization done with a 32.768 kHz crystal (MC306-G-06Q-32.768, manufacturer JFVNY) with two 6.8 pF

loading capacitors.

3. Wakeup with code execution from Flash memory. Average value given for a typical wakeup time as specified in Table 45.
