The output voltage for DCDC3 is switched between the value defined in DEFDCDC3_LOW and
DEFDCDC3_HIGH depending on the status of the DEFDCDC3 pin. IF DEFDCDC3 is LOW the value in
DEFDCDC3_LOW is selected, if DEFDCDC3 = HIGH, the value in DEFDCDC3_HIGH is selected. Per default
the converter is internally fixed but can be programmed to an externally adjustable version by EEPROM similar to
DCDC2.
