| uint8_t hdcd_state::arg |
arg is set when a packet prefix is found.
control is the active control code, where bit 0-3: target_gain, 4-bit (3.1) fixed-point value bit 4 : peak_extend bit 5 : transient_filter bit 6,7: always zero

| int hdcd_state::gain_counts[16] |
target_gain is a 4-bit (3.1) fixed-point value, always negative, but stored positive.
The 16 possible values range from -7.5 to 0.0 dB in steps of 0.5, but no value below -6.0 dB should appear.
