Enhanced Full Scale (2x) Transmit and Receive Mode.
0 = Default
1 = Transmit/Receive 2x Full Scale
This bit changes the full scale of the ADC and DAC from 0 min to +6 dBm into 600  load (or
1.5 dBV into all reference impedances). When this bit is set, low loop currents may result in
increased distortion.
AC Impedance Selection.
The off-hook ac termination is selected from the following:
0 = 600 
1 = 270  + (750  || 150 nF) and 275  + (780  || 150 nF)
