Clipping defined for 1% output distorsion.
All internal stages outputs are monitored.
Flashed during analog to digital converter calibration
process. Calibration is engaged at power up, and after
each changes on sampling frequency, bit width or clock
source.
Illuminated if all internal suply voltages are correct.
