Mute input to INVROUT2 mixer
Mute input to INVROUT2 mixer
AUXR input to ROUT2 inverter gain
000 = -15dB
...
111 = +6dB
0 = mute AUXR beep input
1 = enable AUXR beep input
Microphone Bias Voltage Control
0 = 0.9 * AVDD
1 = 0.65 * AVDD
Reserved
Connect R2 pin to right channel input PGA
positive terminal.
0=R2 not connected to input PGA
1=R2 connected to input PGA amplifier positive
terminal (constant input impedance).
Connect RIN pin to right channel input PGA
negative terminal.
0=RIN not connected to input PGA
1=RIN connected to right channel input PGA
amplifier negative terminal.
Connect RIP pin to right channel input PGA
amplifier positive terminal.
0 = RIP not connected to input PGA
1 = right channel input PGA amplifier positive
terminal connected to RIP (constant input
impedance)
Reserved
Connect L2 pin to left channel input PGA
positive terminal.
0=L2 not connected to input PGA
1=L2 connected to input PGA amplifier positive
terminal (constant input impedance).
Connect LIN pin to left channel input PGA
negative terminal.
0=LIN not connected to input PGA
1=LIN connected to input PGA amplifier
negative terminal.
Connect LIP pin to left channel input PGA
amplifier positive terminal.
0 = LIP not connected to input PGA
1 = input PGA amplifier positive terminal
connected to LIP (constant input impedance)
INPPGAVOLL and INPPGAVOLR volume do
not update until a 1 is written to
INPPGAUPDATE (in reg 45 or 46)
Left channel input PGA zero cross enable:
0=Update gain when gain register changes
1=Update gain on 1^st zero cross after gain
register write.
Mute control for left channel input PGA:
0=Input PGA not muted, normal operation
1=Input PGA muted (and disconnected from the
following input BOOST stage).
