0
Selects normal operating mode.
Analog loopback mode. Loops the transmitted analog
signal back to the receiver, and causes the receiver to
use the same center frequency as the transmitter. To
squelch the TXA pin, transmit enable must be forced
low.
0

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 carrier from TXA pin.
0
Selects normal operation.
D2
Reset
1
Resets modem to power down state. All control
register bits (CR0, CR1, Tone) are reset to zero. The
output of the CLK pin will be set to the crystal frequency.
0
Selects 11.0592 MHz crystal echo output at CLK pin.
D3
CLK Control
(Clock Control)
1
Selects 16 X the data rate, output at CLK pin in DPSK
modes only.
