Transmit Mute.
0 = Transmit signal is not muted.
1 = Mutes the transmit signal.
Analog Transmit Attenuation.
000 = 0 dB attenuation
001 = 3 dB attenuation
010 = 6 dB attenuation
011 = 9 dB attenuation
1xx = 12 dB attenuation
Note: Write these bits to zero when using the finer resolution transmit and receive gain/attenuation
Receive Mute.
0 = Receive signal is not muted.
1 = Mutes the receive signal.
