(0X00[7])
Enable Front End.
1 = Enable the digital filters and analog front end.
0 = Disable the analog blocks shut off the clocks to the digital and analog receive/transmit
circuits.
SelTX2
(0X00[6])
Select Tx driver 2
1 = Selects Secondary transmitter (TXAP2 and TXAN2) if TXDIS=0
0 = Selects Primary transmitter (TXAP1 andTXAN1) if TXDIS=0
TXBST1
(0X00[5])
1 = Add a gain of 1.335dB (16.6%) to the transmitter; also the common mode voltage of the
transmit path is increased to 1.586 V. This is intended for enhancing DTMF transmit power
only and should not be used in data mode.
0 = No gain is added
TXBST0
(0X00[4])
1 = A gain of 1.65 dB(21%) is added to the transmitter
0 = The gain of the transmitter is nominal
TXDIS
(0X00[3])
1 = Tri-state the TXAP1,2 and TXAN1,2 pins, provides a bias of VBG into 80 k
for each
output pin
RXG(1:0)
(0X00[2:1]) Rx Gain Selection
00 = 6 dB Receive Gain
01 = 9 dB
10 = 12 dB
11 = 0 dB
RXGAIN
(0X00[0])
20 dB RxGain Enable. This gain selection can be used for line snoop or Caller
ID detection.
1 = Increase the gain of the receiver by 20 dB.
0 = Normal operation
