Reset R/W Description
2 (10) R/W Sets the level of hysteresis on the magnitude deviation
(internal AGC signal that determines 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
1 (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.

0 (00) R/W 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 freezes 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.
1 (01) R/W Sets the averaging length for the amplitude from the channel
filter. Sets the OOK decision boundary for OOK reception.
