Description
Always write as 0 if writing to this register.
Description
Used to control the maximum gain in the range of 0 dB to 15 dB. This is
the maximum gain
that can be applied to the input signal in order to reach the desired
output level.
0x0 = 15 dB
0x1 = 14 dB
0x2 = 13 dB
0x3 = 12 dB
0x4 = 11 dB
0x5 = 10 dB
...
0xF = 0 dB
Used to control the decay time in the range of 20 ms to 12 sec. The
decay time
corresponds to the time required for the output to reach the desired
level.
0x0 = 20 ms
0x1 = 100 ms
0x2 = 200 ms
0x3 = 500 ms
0x4 = 1 sec
0x5 = 2 sec
0x6 = 3 sec
0x7 = 4 sec
0x8 = 5 sec
0x9 = 6 sec
0xA = 7 sec
0xB = 8 sec
0xC = 9 sec
0xD = 10 sec
