Force Low Voltage DC Termination Mode.
0 = Normal gain.
1 = When the DCT[1:0] bits are set to 10b (FCC mode), setting this bit will force the Low Voltage
dc termination mode while allowing for a transmit level of –1 dBm. See "4.13. DTMF Dialing" on
page 19.
This bit is used to enable the on-hook line monitor ADC and the line voltage monitor.
MODE
Notes:
When set, the ring detection circuitry provides full-wave rectification. This will affect the RGDT pin
as well as the data stream presented on SDO during ring detection.
0 = Half Wave.
1 = Full Wave.
Ring Detect Network Squelch.
This bit must be set, then cleared after at least 1 ms, following a polarity reversal or ring signal
detection. It is used to quickly recover the offset on the RNG1/2 pins after a polarity reversal or
ring signal. If the SQL2 bit is enabled during CID data reception, this bit should not be used.
0 = Normal operation.
1 = Squelch function is enabled.
