Bits[7:5] Hold These register bits control the hold time for the limiter, which is the time in ms
time that the limiter
holds the attenuated level after the current input to the limiter function falls
below the limiter
threshold.
0x0 = 0 ms
0x1 = 10 ms
0x2 = 20 ms
0x3 = 30 ms
0x4 = 40 ms
0x5 = 50 ms
0x6 = 60 ms
0x7 = 70 ms
Bits[4:0] Decay These register bits control the decay time for the limiter in the range of 10 dB/s
time to 320 dB/s in
10 dB/s steps.
