D2 selects 4-wire full duplex in the modulation mode
selected. The receive path corresponds to the receive
mode selected by the ANS/ORIG bit CR0 D0 in terms of
high or low band selection. 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.
