Figure 156: Region of NER comparison
NER requires a positive value for TOLR, otherwise it may not function
properly. The TOLR value can be set using SETRGAPC.
NER function blocks do not have the hysteresis feature. Oscillating
outputs should be avoided when comparing analog signals that have
closely varying values.
