R/W Sets the level of hysteresis on the magnitude deviation
(internal AGC signal that determines gain changes).
00 No hysteresis, small symmetric dead zone, high gain
01
Low hysteresis, small asymmetric dead zone, medium
gain
10
Medium hysteresis, medium asymmetric dead zone,
medium gain
11 Large hysteresis, large asymmetric dead zone, low gain
01
R/W Sets the number of channel filter samples from a gain
adjustment has been made until the AGC algorithm starts
accumulating new samples.

R/W Controls when the AGC gain should be frozen.
00 Normal operation. Always adjust gain when required.
01
The gain setting is frozen when a sync word has been
found.
10
Manually freeze the analog gain setting and continue to
adjust the digital gain.
11
Manually freezes both the analog and the digital gain
settings. Used for manually overriding the gain.
01
R/W Sets the averaging length for the amplitude from the channel
filter. Please use the SmartRF Studio software [8] for
recommended settings.
