Description
Reserved
Amplifier Mute (AM): Mute is not supported by
this widget.
Amplifier Gain (AG): This field returns the Gain
setting for the amplifier requested. If the amplifier
requested does not exist, all ‘0’s will be returned.
Default equals 0 dB.
Bits [15:0]
Payload = xxxxh
Description
Set Output Amplifier (SOA): This bit deter-
mines whether the value programmed refers to
the output amplifier. This bit should always be ‘0’
since an output amplifier is not present on this
widget.
Set Input Amplifier (SIA): This bit determines
whether the value programmed refers to the
input amplifier. Set to a 1 for the value to be
accepted.
Set Left Amplifier (SLA): Selects the left chan-
nel (channel 0). A 1 indicates that the relevant
amplifier should accept the value being set. If
both bits are set, both amplifiers are set.
Set Right Amplifier (SRA): Selects the right
channel (channel 1). A 1 indicates that the rele-
vant amplifier should accept the value being set.
If both bits are set, both amplifiers are set.
Index (IDX): This field is used when program-
ming the input amplifiers on Selector Widgets
and Sum Widgets. This field is ignored.
Mute (MUTE): When ‘0’, the Mute is inactive.
This field is ignored.
Gain (GAIN): Specifies the amplifier gain in dB.
xxxxx00b = 0 dB
xxxxx01b = +10 dB
xxxxx10b = +20 dB
xxxxx11b = +30 dB
Bits(6:2) are not used and are ignored.
