Description

Default

Bits[7:5]

Hold time

These register bits control the hold time for the limiter, which is the time in ms that the limiter

holds the attenuated level after the current input to the limiter function falls below the limiter

threshold.

000

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 time

These register bits control the decay time for the limiter in the range of 10 dB/s to 320 dB/s in

10 dB/s steps.
