HYST_LEVEL[1:0]
2 (10)
R/W
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

has been made until the AGC algorithm starts accumulating new
samples.

R/W
Control 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 analogue gain setting and continue
to adjust the digital gain.
3 (11)
Manually freezes both the analogue and the digital gain
setting. Used for manually overriding the gain.
