The HP filter on the AIC does work, but it's poor at reducing low frequency noise (<15Hz).
RED: Fc = 10Hz ORG: Fc = 5000Hz Note: Plot is with the 60Hz HP prefilter enabled
The register settings do provide the correct cutoff frequency (checked in Matlab) and 1st order roll-off.
Instead, use a software HP filter to cut down this noise.
