Reserved, must be set to 0
The result is stable 1 ms after enabling. The setup time for switching between
two thresholds is negligibly small.
For power management reasons, the battery voltage monitor should be
switched off by setting bit[13:10] to zero when the measurement is completed.

is zero), the clock for the DC/DC converters is directly derived
from the crystal frequency (nominal 18.432 MHz). Otherwise, the synthesizer
clock is used as the reference (please refer to the respective column in
Table 2–1 on page 11).
