7SR
Software Reset.
0 = Enables the DAA for normal operation.
1 = Sets all registers to their reset value.
Note:
Bit automatically clears after being set.

Reserved
Read returns zero.

PWMM[1:0]
Pulse Width Modulation Mode.
Used to select the type of signal output on the call progress AOUT pin.
00 = PWM output is clocked at 16.384 MHz as a delta-sigma data stream. A local density of
1s and 0s tracks the combined transmit and receive signals. Use this setting with the optional
call progress circuit shown in Figure 19 on page 20.
01 = Balanced conventional PWM output signal has high and low portions of the modulated
pulse that are centered on the 16 kHz sample clock.
10 = Conventional PWM output signal returns to logic 0 at regular 32 kHz intervals and rises
at a time in the 32 kHz period proportional to its instantaneous amplitude.
11 = Reserved.
3
PWME
Pulse Width Modulation Enable.
0 = Pulse width modulation mode disabled (AOUT).
1 = Enable pulse width modulation mode for the call progress analog output (AOUT). This
mode sums the transmit and receive audio paths and presents this as a CMOS digital-level
output of PWM data. The circuit in Figure 19 on page 20 should be used.
2
Reserved
Read returns zero.
1IDL
Isolation Digital Loopback.
0 = Digital loopback across the isolation barrier is disabled.
1 = Enables digital loopback mode across the isolation barrier. The line-side device must be
enabled and off-hook prior to setting this mode. The data path includes the TX and RX filters.
0
Reserved
Read returns zero.
