Near zero detection
Specify a positive value for Threshold High and a negative value (with sign) for Thresh-
old Low. Positive values for the low threshold or negative values for the high threshold
are not allowed. As soon as the source signal is within these limits, the Near Zero Flag is
set.

If the source signal is invalid, no further values are calculated. All output values are fro-
zen (remain unchanged). As soon as the source signal is valid again, new values are
calculated.

Depending on the control bits, input 1, input 2, input 3 or input 4 is outputted.

If one of the source signals is invalid, the output signal will become invalid as well.
