Description
Enable/Disable gain monitoring
Minimum signal level above which gain monitoring will be
exercised. MSB 16 bits of I
Configuration to explicitly enable/disable high gain over range
detection
Configuration to explicitly enable/disable low gain under range
detection
High gain threshold above which a model switch can be initiated
by the gain monitoring hardware. Only applicable if gain
overrange detection is enabled
Low gain threshold(attenuation) below which a model switch can
be initiated by the gain monitoring hardware. Only applicable if
gain under range detection is enabled.
Model to switch to on violation of high gain threshold
Model to switch to on violation of low gain threshold
Controls the number of samples over which gain is averaged.
