ZSEXT
Impedance Internal Reference Resistor Disable.
When enabled, this bit removes the internal reference resistor used to synthesize ac
impedances for 600 + 2.1
μ
F and 900 + 2.16
μ
F so that an external resistor reference
may be used.
0 = Internal resistor used to generate 600 + 2.1
μ
F and 900 + 2.16
μ
F impedances.
1 = Internal resistor removed from circuit.
3
SWDB
Battery Switch Debounce (Si3211 and Si3212 only).
When enabled, this bit allows debouncing of the battery switching circuit only when tran-
sitioning from V
BATH
to V
BATL
external battery supplies (EXTBAT = 1).
0 = No debounce used.
1 = 60 ms debounce period used.
Si3210 = Reserved.
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 (Si3210 only).
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.
