4.3. SLIC Control
See descriptions of linefeed interface and power monitoring for guidelines on computing register values. All values
are represented in twos-complement format.
Note: The values of all indirect registers are undefined following the reset state. Shaded areas denote bits that can be read

and written but should be written to zeroes.
Loop Closure Threshold.
Loop closure detection threshold. This register defines the upper bounds threshold if hys-
teresis is enabled (direct Register 108, bit 0). The range is 0–80 mA in 1.27 mA steps.
Ring Trip Threshold.
Ring trip detection threshold during ringing.
Common Mode Minimum Threshold for Speed-Up.
This register defines the negative common mode voltage threshold. Exceeding this
threshold enables a wider bandwidth of dc linefeed control for faster settling times. The
range is 0–23.625 V in 0.375 V steps.
Common Mode Maximum Threshold for Speed-Up.
This register defines the positive common mode voltage threshold. Exceeding this
threshold enables a wider bandwidth of dc linefeed control for faster settling times. The
range is 0–23.625 V in 0.375 V steps.
Power Alarm Threshold for Transistors Q1 and Q2.
