bit or enabling the ADC, the user must always allow the reference to start up before the output
from the Analog Comparator or ADC is used. To reduce power consumption in Power-down
mode, the user can avoid the three conditions above to ensure that the reference is turned off
before entering Power-down mode.” on page
