Read returns 0.
Minimum Operational Loop Current.
Adjusts the minimum loop current at which the DAA can operate. Increasing the minimum
operational loop current can improve the signal headroom at a lower TIP/RING Voltage.

Read returns 0.
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.
Read returns 0.
DC Impedance Selection.
0 - Normal DC Impedance. This mode should be used for all standard applications.
1 = 800? DC termination.
On-Hook Speed.
This bit works in combination with the OHS2 bit (U62, bit 8) to set the on-hook speed. The on-hook
speeds are measured from the time the OH bit is cleared until loop current equals zero.
OHS
Read returns 0.
TIP/RING Voltage Adjust.
These bits affect the TIP/RING voltage on the line. Low voltage countries should use a lower
TIP/RING voltage. Raising the TIP/RING voltage can improve signal headroom.
