Table 52. ADC_ALC_7 (0x87h)
Bits
Field
Description
5:0
MAX_LEVEL
This sets the maximum allowed gain of the volume control to the output amplifier whenever
the ALC is use. If the volume control is less than 6 bits the relevant LSBs are used as the
limit and the MSBs are ignored.
Table 53. ADC_ALC_8 (0x88h)
Bits
Field
Description
5:0
MIN_LEVEL
This sets the minimum allowed gain of the volume control to the output amplifier whenever
the ALC is use. If the volume control is less than 6 bits the relevant LSBs are used as the
limit and the MSBs are ignored.
