Updated Assembly code example in
after setting the ACBG bit or enabling the ADC, the user must always
allow the reference to start up before the output from the Analog Compar-
ator 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
