ALC1: ALC1 Enable
0: ALC1 Disable (Default)
1: ALC1 Enable
When ALC1 bit is
1
, the ALC1 operation is enabled.
ALC2: ALC2 Enable
0: ALC2 Disable
1: ALC2 Enable (Default)
After completing the initializing cycle (512/fs = 64ms @fs=8kHz at ROTM bit =
0
), the ALC2 operation is
enabled. When the PMSPK bit changes from
0
to
1
or PDN pin changes from
L
to
H
, the initilization
cycle starts.

REF6-0: Reference value at ALC1 Recovery Operation (See Table 41)
During the ALC1 recovery operation, if the IPGA value exceeds the setting reference value by gain operation,
then the IPGA does not become larger than the reference value. For example, when REF7-0 =
30H
, RATT =
2step, IPGA = 2FH, even if the input signal does not exceed the
ALC1 Recovery Waiting Counter Reset
Level
, the IPGA does not change to 2FH + 2step = 31H, and keeps 30H. Default is
36H
.
