Attenuation. Each bit represents 0.5dB of attenuation to be
applied to the channel. The range will be -125dB to 2dB as
follows:
0x00: +2dB
0x01: +1.5dB
0x02: +1.0dB
...
0x47: -33.5dB
0x48: -34.0dB
0x49: -34.5dB
...
0xFE: -125dB
0xFF: Hard Master Mute
1 = auto mute if detect long strings of zeros on input
1 = clear limit 0/1 latches, see STATUS register
Reserved
1 = units for step_time are 10ms
0 = units for step_time are 1ms
1 = step volume progressively to new setting
1 = disable all gain functions (bypass gain multiply)
1 = change gain immediately
0 = change on zero cross
1 = hard mute after reset, 0 = soft mute
