ADF2:TE1 = 1 indicates that the C/I-channel 1 in the TE mode can be
accessed and that the C/I-channel on IOM
transparently from the transceiver core to the IOM
C/I-code
ADF2:TE1 = 0 sets the normal mode. The two bits are set to "0"
Contain the C/I-command coming from the IOM
Set to "1"
These bits are the MSBs of the 6-bit wide C/I code in IOM
ADF2:TE1 = 1.
If ADF2:TE1 = 0 these two bits have no effect. They should however be set
to 1 for future compatibility
Contain the C/I-code going to the IOM
Set to "1"
