Sets the level of hysteresis on the magnitude deviation
(internal AGC signal that determine gain changes).
Setting Description
0 (00)
No hysteresis, small symmetric dead zone,
high gain
1 (01)
Low hysteresis, small asymmetric dead zone,
medium gain
2 (10)
Medium hysteresis, medium asymmetric dead
zone, medium gain
3 (11)
Large hysteresis, large asymmetric dead
zone, low gain
Sets the number of channel filter samples from a gain

Controls when the AGC gain should be frozen.
Setting Function
0 (00)
Normal operation. Always adjust gain when
required.
1 (01)
The gain setting is frozen when a sync word has
been found.
2 (10)
Manually freeze the analog gain setting and
continue to adjust the digital gain.
3 (11)
Manually freezes both the analog and the digital
gain settings. Used for manually overriding the
gain.
Sets the averaging length for the amplitude from the channel
filter.
