Force Japan DC Termination.
0 = Normal mode.
1 = Force Japan dc termination.
DTMF Dialing Mode.
This bit should be set during DTMF dialing in CTR21 mode if SDB (LVCS) < 12.
0 = Normal operation.
1 = Increase headroom for DTMF dialing.
Line Voltage Adjust.
0 = Nominal.
1 = Decreases dc termination voltage.
Force Low Voltage Mode.
When SF5[3:2] (DCT) = 10
(see DCT = 00) while allowing for a transmit level of –1 dBm.
