1. Guaranteed by characterization results, not tested in production, unless otherwise specified.
2. LCD enabled with external VLCD, static duty, division ratio = 256, all pixels active, no LCD connected.
3. LCD enabled with external VLCD, 1/8 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD connected.
4. Based on characterization done with a 32.768 kHz crystal (MC306-G-06Q-32.768, manufacturer JFVNY) with two 6.8 pF
loading capacitors.
5. Guaranteed by test in production.
6. When MSI = 64 kHz, the RMS current is measured over the first 15 µs following the wakeup event. For the remaining part
of the wakeup period, the current corresponds the Run mode current.
