The output voltage for DCDC2 is switched between the value defined in DEFDCDC2_LOW and
DEFDCDC2_HIGH depending on the status of the DEFDCDC2 pin. IF DEFDCDC2 is LOW the value in
DEFDCDC2_LOW is selected, if DEFDCDC2 = HIGH, the value in DEFDCDC2_HIGH is selected. Per default
the converter is internally fixed but can be programmed to an externally adjustable version by EEPROM similar to
DCDC1.
