Selects answer mode (transmit in high band, receive
in low band).
D0
Answer/

1
Selects originate mode (transmit in low band, receive in
high band).
0
Disables transmit output at TXA.
D1
Transmit
Enable
1
Enables transmit output at TXA.
Note: TX Enable must be set to 1 to allow Answer Tone
and DTMF Transmission as well as data carriers.

Selects power-down mode. All functions disabled except
digital interface.

1
Internal synchronous mode. In this mode TXCLK is an
internally derived 1200 Hz signal. Serial input data
appearing at TXD must be valid on the rising edge of
TXCLK. Receive data is clocked out of RXD on the
falling edge of RXCLK.
0
0
1
0
External synchronous mode. Operation is identical to
internal synchronous, but TXCLK is connected internally
to EXCLK pin, and a 1200 Hz ± 0.01% clock must be
supplied externally.
0

1
Slave synchronous mode. Same operation as other
synchronous modes. TXCLK is connected internally to
the RXCLK pin in this mode.
