SBOS644C February 2013 – March 2018 INA231
The Configuration register settings control the operating modes for the INA231. This register controls the conversion time settings for both the shunt and bus voltage measurements, as well as the averaging mode used. The operating mode that controls which signals are selected to be measured is also programmed in the Configuration register.
The Configuration register can be read from at any time without impacting or affecting the device settings or a conversion in progress. Writing to the Configuration register halts any conversion in progress until the write sequence is complete, resulting in the start of a new conversion based on the new contents of the Configuration register. This feature prevents any uncertainty in the conditions used for the next completed conversion.
|Bit 15||Setting this bit to 1 generates a system reset that is the same as a power-on reset; all registers are reset to default values. This bit self-clears.|
|Bits 9–11||These bits set the number of samples that are collected and averaged together. Table 5 summarizes the AVG bit settings and related number of averages for each bit.|
