10.8.2 Registers
10.8.2.1
The RTopMux and RBotMux bits control the connection
of the two ends of the resistor string. The RTopMux bit
controls the top end of the resistor string, which can
either be connected to Vcc or to the op-amp output. The
RBotMux bits control the connection of the bottom end of
the resistor string.

The RTapMux bits control the center tap of the resistor
string. Note that only relative weighting of units is given
in the table.
The Gain and Loss columns correspond to the gain or
loss obtained if the RTopMux and Gain bits are set so
that the overall amplifier provides gain or loss.
The Gain bit controls whether the resistor string is con-
nected around the op-amp as for gain (center tap to
