bg_trim, bits <2:0>
vref_trim, bits <6:4>
This register contains the idle B keyword.
The reference voltage adjust register allows trimming of
bg_trim, bits <2:0>: Setting these bits adjusts the
bandgap voltage by selecting the value for the on-chip
resistor R2. This resistor trims the PTAT “K” factor.
See On−Chip BandGap Reference and Current Biasing
on page 17
vref_trim, bits <6:4>: Setting these bits adjusts the
reference voltage range (vrefp-vrefm) for the ADCs.
