The moving average filter is considered unstable, if the input to output difference is greater than
.. doxygendefine:: ADC_FILTER_STARTUP_CYCLES

In this case, the :ref:`safety_flags_adc_unstable` flag will be set until the filter output converges within the range for at least

If the input value keeps changing or oscillating, the error flag will be permanently set.
The moving average filter's output signal is the Low Frequency (LF) PT1000 resistance signal used for internal PT1000 measurements.

* - To use or not the peripheral’s drivers in application code(i.e.
* code will be based on direct access to peripheral’s registers
* rather than drivers API), this option is controlled by
