BIT SYMBOL DESCRIPTION
7 to 4 SST[3:0] Start of the stereo blend SNC. See Table 53 and Fig.7.
3 and 2 SSL[1:0] Slope of the stereo blend SNC. See Fig.8.
1 HCMP High cut control source. 0 = control by the level (LEV) detector; 1 = control by the
multipath (MPH) detector.
0 HCSF High cut control minimum bandwidth. 0 = 2 kHz; 1 = 3 kHz.
