Auxiliary Input Mode
0 = inverting buffer
1 = mixer (on-chip input resistor bypassed)
Select AUX amplifier output as input PGA signal
source.
0=AUX not connected to input PGA
1=AUX connected to input PGA amplifier negative
terminal.
Connect MICN to input PGA negative terminal.
0=MICN not connected to input PGA
1=MICN connected to input PGA amplifier negative
terminal.
Connect input PGA amplifier positive terminal to MICP
or VMID.
0 = input PGA amplifier positive terminal connected to
VMID
1 = input PGA amplifier positive terminal connected to
MICP through variable resistor string
Reserved
Input PGA zero cross enable:
0=Update gain when gain register changes
1=Update gain on 1
write.
Mute control for input PGA:
0=Input PGA not muted, normal operation
1=Input PGA muted (and disconnected from the
following input BOOST stage).
Input PGA volume
000000 = -12dB
000001 = -11.25db
.
010000 = 0dB
.
111111 = 35.25dB
Input Boost
0 = PGA output has +0dB gain through input BOOST
stage.
1 = PGA output has +20dB gain through input BOOST
stage.
Reserved
Controls the MICP pin to the input boost stage (NB,
when using this path set MICP2INPPGA=0):
000=Path disabled (disconnected)
001=-12dB gain through boost stage
010=-9dB gain through boost stage
…
111=+6dB gain through boost stage
