Function

2

LCVE

Voltage-Based Loop Closure.

Enables loop closure to be determined by the TIP-to-RING voltage rather than loop cur-

rent.

0 = Loop closure determined by loop current.

1 = Loop closure determined by TIP-to-RING voltage.

1

DCFIL

DC-DC Converter Squelch.

When enabled, this bit squelches noise in the audio band from the dc-dc converter con-

trol loop.

0 = Voice band squelch disabled.

1 = Voice band squelch enabled.

0

HYSTEN Loop Closure Hysteresis Enable.

When enabled, this bit allows hysteresis to the loop closure calculation. The upper and

lower hysteresis thresholds are defined by indirect registers 28 and 43, respectively.

0 = Loop closure hysteresis disabled.

1 = Loop closure hysteresis enabled.
