Software Reset.
0 = Enables DAA for normal operation.
1 = Sets all registers to their reset value.
Note: Bit clears automatically after being set.
Always write as zero. Reads undefined.
Pulse-Width Modulation Mode.
Selects the type of signal on the call progress AOUT pin.
00 = PWM output clocked at 16.384 MHz. A local density of 1s and 0s tracks the com-
bined transmit and receive signal.
01 = Balanced conventional PWM output signal has high and low portions of the modu-
lated pulse centered on the 32 kHz sample clock.
10 = Conventionally PWM output signal returns to 0 at 32 kHz intervals and rises at a
time in the 32 kHz period proportional to the instantaneous amplitude.
11 = Reserved.
Pulse-Width Modulation Enable.
0 = Call progress PWM AOUT disabled.
1 = Call progress PWM AOUT enabled.
Isolation Digital Loopback.
0 = Digital loopback across isolation barrier disabled.
1 = Enables digital loopback mode across isolation barrier. The line-side device must be
enabled and off-hook before setting this mode. This data path includes RX and TX filters.
A valid phone line is not necessary for this mode.
Read returns zero.
Read returns zero.
