Noise blanker sensitivity. These 2 bits determine the noise blanker sensitivity levels;
see Table 30.
De-emphasis. If DE75 = 1, then de-emphasis is 75 s. If DE75 = 1, then de-emphasis
is 50 s.
HCC control switch. With static roll-off: HCCS = 1, C
roll-off: HCCS = 0, C
HCC start alignment. These 2 bits determine the alignment for the start of high cut
control; see Table 31 and Fig.10.
HCC slope alignment. These 2 bits determine the alignment for the slope of high cut
control; see Table 32 and Fig.11.
