R/W
Sets the threshold of useful equalization i.e. the level of any
echo path that must be equalized relative to the frequency
5:3 FTRACKCLIPLEVEL domain noise floor. The default value of 4 relates to an echo
level at approximately –21dB of the main path.

Sets the threshold of useful equalization i.e. the level of any
echo path that must be equalized relative to the time
2:0 TTRACKCLIPLEVEL domain noise floor. The default value of 2 relates to an echo
level at approximately –21dB of the main path.

R/W
Sets the number of tracking periods during which the
enhanced symbol tracker must observe a persistent
change in the channel profile before reacting to it.
Increasing this register value prevents the symbol tracker
reacting to spurious and/or transient events.

Sets the threshold level (FALSEALIASLEVEL) for valid
path energy detection in the channel transfer function used
for symbol tracking.
