DESCRIPTION
D1
D0
0
0
Selects Normal Operating mode.
0
1
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.
Not used.

D1, D0
Test Mode
1
1
Selects local digital loopback. Internally loops TXD back
to RXD and continues to transmit data 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 clock pin will be set to the crystal frequency.
D3
CLK Control
(Clock Control)

0
Not supported in the 73K321.See the TXCLK and RXCLK
pin descriptions for 16x the data rate clocks.
0
Selects normal equalization.
D4
Add Ph. Eq.
1
In V.23 mode, additional phase equalization is added to
the main channel filters when D4 is set to 1.
0
Disables interrupt at
INT
pin. All interrupts are normally
disabled in Power Down modes.
D5

Interrupt
1
Enables
INT
output. An interrupt will be generated with a
change in status of DR bits D1-D3. The special tone and
call progress detect interrupts are masked when the TX
enable bit is set. Carrier detect is masked when TX
DTMF is activated. All interrupts will be disabled if the
device is in Power Down mode.
D7
D6
0
0
Selects normal data transmission as controlled by the
state of the TXD pin.
0
1
Selects an alternating mark/space transmit pattern for
modem testing.

0
1
Selects a constant mark transmit pattern.
Selects a constant space transmit pattern.
