ALC Recovery Operation 

 
ALC recovery operation waits for the WTM2-0 bits (

Table 27

) to be set after completing ALC limiter operation. If the 

input signal does not exceed “ALC recovery waiting counter reset level” (

Table 24

) during the wait time, ALC recovery 

operation is executed. The IVL and IVR values are automatically incremented by RGAIN1-0 bits (

Table 28

) up to the set 

reference level (

Table 29

) with zero crossing detection which timeout period is set by ZTM1-0 bits (

Table 26

). Then the 

IVL and IVR are set to the same value for both channels. ALC recovery operation is executed at a period set by WTM2-0 
bits. When zero cross is detected at both channels during the wait period set by WTM2-0 bits, ALC recovery operation 
waits until WTM2-0 period and the next recovery operation is executed. If ZTM1-0 is longer than WTM2-0 and no zero 
crossing occurs, the ALC recovery operation is executed at a period set by ZTM1-0 bits. 
 
For example, when the current IVL and IVR values are 30H and RGAIN1-0 bits are set to “01”, IVL and IVR values are 
changed to 32H by the auto limiter operation and then the input signal level is gained by 0.75dB (=0.375dB x 2). When 
the IVL and IVR values exceed the reference level (REF7-0 bits), the IVL and IVR values are not increased. 
 
When 

“ALC recovery waiting counter reset level (LMTH1-0) 

≤

 Output Signal < ALC limiter detection level (LMTH1-0)” 

during the ALC recovery operation, the waiting timer of ALC recovery operation is reset. When 

“ALC recovery waiting counter reset level (LMTH1-0) > Output Signal”, 

the waiting timer of ALC recovery operation starts. 
 
The ALC operation corresponds to the impulse noise. When the impulse noise is input, the ALC recovery operation 
becomes faster than a normal recovery operation (Fast Recovery Operation). When large noise is input to microphone 
instantaneously, the quality of small level in the large noise can be improved by this fast recovery operation. The speed of 
fast recovery operation is set by RFST1-0 bits (

Table 30

).
