The Version register holds a 16-bit value that indicates
the version of the device.
register format.
While in active mode, the device periodically measures
the voltage between the V
to 4.98V range. The resulting data is placed in the V
register every 175.8ms with an LSb value of 0.625mV.
Additionally, the device maintains a record of the mini-
mum and maximum voltage measured by the device,
and an average voltage over a time period defined by
the host. Contents of the V
registers are indeterminate for the first conversion cycle
time period after device power-up. The last values of the
V

While in active mode, the device periodically measures the
