AOUT Receive Path Attenuation.
When decremented from the default setting, these bits linearly attenuate the AOUT
receive path signal used for call progress monitoring. Setting the bits to all 0s mutes the
AOUT receive path.
Attenuation = 20 log(ARM[7:0]/64)
1111_1111 = +12 dB (gain)
0111_1111 = +6 dB (gain)
0100_0000 = 0 dB
0010_0000 = –6 dB (attenuation)
0001_0000 = –12 dB

AOUT Transmit Path Attenuation.
When decremented from the default settings, these bits linearly attenuate the AOUT trans-
mit path signal used for call progress monitoring. Setting the bits to all 0s mutes the AOUT
transmit path.
Attenuation = 20 log(ATM[7:0]/64)
