The DC/DC converters are up-converters only. Thus, if the battery voltage is
higher than the selected nominal voltage, the output voltage will exceed the
nominal voltage.

Note, that the reference voltage for DC/DC converter 1 is derived from the
main reference source supplied via pin AVDD1. Therefore, if this DC/DC con-
verter is used, its output must be connected to the analog supply.
The DC/DC converters are up-converters only. Thus, if the battery voltage is
higher than the selected nominal voltage, the output voltage will exceed the
nominal voltage.
