Question regarding ADAU1446 DSP signal detector

I'm using ADAU1446 audio DSP.

Regarding signal detector block in the DSP, when we inject audio signal and read the detected value from the detector, we can get a 6digit hexa number like

"0x554719" and "0x2A3EE5".


I wander that the numbers represent dB (decibel) or real voltage??


There is no description regarding the number in the datasheet.
