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 must be low.
Tone Register bit D2 must be zero.
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.
D1, D0
Test Mode
1
1
Selects local digital loopback. Internally loops TXD back to
RXD and continues to transmit data carrrier at TXA pin.
Selects normal operation.
0
D2
Reset
1
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
1
Selects 11.0592 MHz crystal echo output at CLK pin.
D3
CLK Control
(Clock Control)
Selects 16 X the data rate output at CLK pin in QAM and
DPSK only.
