Current Limiting Enable.
0 = Current limiting mode disabled.
1 = Current limiting mode enabled. This mode limits loop current to a maximum of 60 mA per
the TBR21 standard.
DC Impedance Selection.
0 = 50  dc termination is selected. This mode should be used for all standard applications.
1 = 800  dc termination is selected.
