7.29.1.18. GAINCTRL_HI Register
Prior to WC revision, this register reset by POR/DAFG/ULR. WC revision, reset by POR only. Writing
to NID22h verb 77F will cause reset on all silicon revisions.
7.29.1.19. GAINCTRL_LO Register
Prior to WC revision, this register reset by POR/DAFG/ULR. WC revision, reset by POR only. Writing
to NID22h verb 77F will cause reset on all silicon revisions.

enable mute if input consecutive zeros exceeds this length:
00 = 32
01 = 1000
10 = 2000
11 = 4000
step time units = 1<<step_time, units in GAINCTRL_LO bit 5
Always 0. It isn’t necessary to provide threshold resolution to
the point where these lower 8 bits would be used.
Always 0. It isn’t necessary to provide threshold resolution to
the point where these lower 8 bits would be used.
8’hFF would equal threshold level of +2.0dB. Each step below
this 8-bit full scale value reduces threshold level by 0.0078 dB.
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
