Read returns zero.
Audio Squelch.
0 = No squelch.
1 = STIPAC and SRINGAC pins squelched.
Capacitor Bypass.
0 = Capacitors CP (C1) and CM (C2) in circuit.
1 = Capacitors CP (C1) and CM (C2) bypassed.
External Transistor Bias Enable.
0 = Bias disabled.
1 = Bias enabled.
External Transistor Bias Levels—On-Hook Transmission State.
DC bias current which flows through external BJTs in the on-hook transmission state.
Increasing this value increases the compliance of the ac longitudinal balance circuit.
00 = 4 mA
01 = 8 mA
10 = 12 mA
11 = Reserved
External Transistor Bias Levels—Active Off-Hook State.
DC bias current which flows through external BJTs in the active off-hook state. Increasing
this value increases the compliance of the ac longitudinal balance circuit.
00 = 4 mA
01 = 8 mA
10 = 12 mA
