8.6.2.1 Configuration Register (address = 00h) [reset = 7127h]
The Configuration register settings control the operating modes for the shunt- and bus-voltage measurements for
the three input channels. This register controls the conversion time settings for both the shunt- and bus-voltage
measurements and the averaging mode used. The Configuration register is used to independently enable or
disable each channel, as well as select the operating mode that controls which signals are selected to be
measured.
This register can be read from at any time without impacting or affecting either device settings or conversions in
progress. Writing to this register halts any conversion in progress until the write sequence is completed, resulting
in a new conversion starting, based on the new Configuration register contents. This architecture prevents any
uncertainty in the conditions used for the next completed conversion.

Description
15
RST
R/W
0h
Reset bit. Set this bit = 1 to generate a system reset that is the
same as a power-on reset (POR). This bit resets all registers to
default values and self-clears.
14
CH1en
R/W
7h
Channel enable mode. These bits allow each channel to be
independently enabled or disabled.
0 = Channel disable
1 = Channel enable (default)

CH2en
12
CH3en
11-9
AVG2-0
R/W
0h
Averaging mode. These bits set the number of samples that are
collected and averaged together.
000 = 1 (default)
001 = 4
010 = 16
011 = 64
100 = 128
101 = 256
110 = 512
111 = 1024
8-6
VBUSCT2-0
R/W
4h
Bus-voltage conversion time. These bits set the conversion time
for the bus-voltage measurement.
000 = 140

110 = 4.156 ms
111 = 8.244 ms
5-3
VSHCT2-0
R/W
4h
Shunt-voltage conversion time. These bits set the conversion
time for the shunt-voltage measurement.
The conversion-time bit settings for VSHCT2-0 are the same as
VBUSCT2-0 (bits 8-6) listed in the previous row.
2-0
MODE3-1
R/W
7h
Operating mode. These bits select continuous, single-shot
(triggered), or power-down mode of operation. These bits default
to continuous shunt and bus mode.
000 = Power-down
001 = Shunt voltage, single-shot (triggered)
010 = Bus voltage, single-shot (triggered)
011 = Shunt and bus, single-shot (triggered)
100 = Power-down
101 = Shunt voltage, continuous
110 = Bus voltage, continuous
111 = Shunt and bus, continuous (default)
