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.
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.

Power Down Line-Side Chip.
0 = Normal operation. Program the clock generator before clearing this bit.
1 = Places the Si3012 in power down or reset state.
Power Down.
0 = Normal operation.
1 = Powers down the Si3021. A pulse on RESET is required to restore normal operation.
