Charge Pump Enable.
0 = Charge pump is disabled.
1 = Charge pump is enabled. (The V
A
pin should not be connected to a supply.
V
D
= 3.3 V ± 10%.)
AOUT Transmit Path Level Control.
00 = –20 dB transmit path attenuation for call progress AOUT pin only.
01 = –32 dB transmit path attenuation for call progress AOUT pin only.
10 = Mutes transmit path for call progress AOUT pin only.
11 = –26 dB transmit path attenuation for call progress AOUT pin only.

AOUT Receive Path Level Control.
00 = 0 dB receive path attenuation for call progress AOUT pin only.
01 = –12 dB receive path attenuation for call progress AOUT pin only.
10 = Mutes receive path for call progress AOUT pin only.
11 = –6 dB receive path attenuation for call progress AOUT pin only.
