The typical values are given for VDD = 3.0 V and max values are given for VDD = 3.6 V, unless otherwise specified.

Based on characterization, not tested in production, unless otherwise specified.

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

loading capacitors.

Tested in production.
