DESCRIPTION
D4
Bypass
Scrambler
0
Selects normal operation. DPSK and QAM data is
passed through scrambler.
1
Selects Scrambler bypass. Bypass DPSK and QAM
data is route around scrambler in the transmit path.
Disables interrupt at
INT
pin. All interrupts are normally
disabled in power-down mode.
D5
Enable Detect
Interrupt
0
1
Enables INT output. An interrupt will be generated with a
change in status of DR bits D1- D4 and D6. The answer
tone and call progress detect interrupts are masked
when the TX enable bit is set. Carrier detect is masked
when TXDTMF is activated. All interrupts will be
disabled if the device is in power-down mode.

Transmit
Pattern
0 0
Selects normal data transmission as controlled by the
state of the TXDpin.
0 1
Selects an alternating mar/space transmit pattern for
modem testing and handshaking. Also used for S1
pattern generation (see CR2 bit D4).
1 0
Selects a constant mark transmit pattern.
1 1
Selects a constant space transmit pattern.

Indicates low received signal quality (above average
error rate). Interacts with Special Register bits D2, D1.

Call Progress
0
No call progress tone detected.
Detect
1
Indicates presence of call progress tones. The call
progress detection circuitry is activated by energy in the
normal 350 to 620 Hz call progress bandwidth.
