D2 selects 4-wire full duplex in the modulation mode
selected. The receive path corresponds receive mode
selected by the ANS/ORIG bit CR0 D0 in terms of high or
low band operation. The transmitter is in the same band
as the receiver, but does not have magnitude filtering or
equalization on its signal as in the receive path.
