temporary spikes in data from causing a failing
status response by filtering raw data from the
self-test before sending a pass/fail status. The
module stores both the raw data and the
filtered data in the HICSTx and LOCSTx
registers. Users may access this data should
they be concerned about these energy spikes.
The temperature sensor data is useful for
temperature compensation of the rate data and
is also directly available to the user. To get the
temperature sensor data users must simply
execute a read command of the TEMx
registers from the device.
