RMS compression curve vs PARAM file values

Hello all,

I am using AD ADAU1452 DSP in multimedia system and need to control the compression curve of the RMS limiter while the system is running (accessing the registers of the DSP via SPI).

I am using Dynamic Processors->RMS->Full Range->No Ext Detector In->1-Ch->RMS (no gain) block in my project. When I export system files I cannot find the exact relation between RMS Compressor block compression curve and parameters in xxyyzz_PARAM.h file (MOD_COMPRESSOR2_ALG0_MONONOPOSTGAINS300FULLRANGE1POINTSxx_VALUE).

Can someone provide me formulas for calculating these values in PARAM.h file?
