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

LCD enabled with external VLCD, static duty, division ratio = 256, all pixels active, no LCD connected.

LCD enabled with external VLCD, 1/8 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD connected.

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

loading capacitors.

Tested in production.

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.
