CONFIGURATION REGISTER
RS2, RS1, RS0 = 010; Power-On/Reset = 0x000117
The configuration register is a 24-bit register from which data
can be read or to which data can be written. This register is
used to configure the ADC for unipolar or bipolar mode, to
enable or disable the buffer, to enable or disable the burnout
currents, to select the gain, and to select the analog input
channel.

Table 21 outlines the bit designations for the configuration register.
CON0 through CON23 indicate the bit locations. CON denotes
that the bits are in the configuration register. CON23 denotes
the first bit of the data stream. The number in parentheses
indicates the power-on/reset default status of that bit.
