 41      If no internal reference is specified, the channel will default to the
 42      external reference defined by vrefin-supply (or vref-supply).
 43      vrefin-supply will take precedence over vref-supply if both are defined.
 44
 45      If no supplies are defined, the reference selection will default to
 46      4096mV internal reference.
