Description
Mute Capable (MC): Supports muting.
Reserved
Step Size (SS): Indicates that the size of each
amplifier’s step gain is 1.0dB
Reserved
Number of Steps (NOS): There are 64 gain
steps; Gain range is from +12dB to -51dB in 1.0dB
steps.
If analog input pin widget is selected as input
source, then the range of +12dB to -12dB is from
analog PGA and the range of -13dB to -51dB is
digital volume control.
If the digital mic input pin widget is selected as the
input source, then the entire gain range from
+12dB to -51dB is digital volume control.
Reserved
Offset (OFST): Indicates that if “0110011b” is pro-
grammed into the Amplified Gain Control, it would
result in a gain of 0dB.
