1
Selects normal operating mode.
Analog loopback mode. Loops the transmitted analog
signal back to the receiver, and causes the receiver to use
the same carrier frequency as the transmitter. To squelch
the TXA pin, TRANSMIT ENABLE bit as well as Tone Reg
bit D2 must be low.
1
0
Selects remote digital loopback. Received data is looped
back to transmit data internally, and RXD is forced to a
mark. Data on TXD is ignored.

1
Selects local digital loopback. Internally loops TXD back to
RXD and continues to transmit data carrier at TXA pin.
0
1
Selects normal operation.
D2
Reset
Resets modem to power down state. All control register bits
(CR0, CR1, CR2, CR3 and Tone) are reset to zero except
CR3 bit D2. The output of the clock pin will be set to the
crystal frequency.
0
Selects 11.0592 MHz crystal echo output at CLK pin.
D3
Clock Control
1
Selects 16 X the data rate, output at CLK pin in DPSK/QAM
modes only.
