Digital Programmable Gain/Attenuation
See functional description sections of digital programmable gain/attenuation for guidelines on computing register
values. All values are represented in twos-complement format.
Note: The values of all indirect registers are undefined following the reset state. Shaded areas denote bits that can be read

Receive Path Digital to Analog Converter Gain/Attenuation.
This register sets gain/attenuation for the receive path. The digitized signal is effectively mul-
tiplied by DACG to achieve gain/attenuation. A value of 0x00 corresponds to – dB gain
(mute). A value of 0x400 corresponds to unity gain. A value of 0x7FF corresponds to a gain
of 6 dB.
Transmit Path Analog to Digital Converter Gain/Attenuation.
This register sets gain/attenuation for the transmit path. The digitized signal is effectively
multiplied by ADCG to achieve gain/attenuation. A value of 0x00 corresponds to – dB gain
(mute). A value of 0x400 corresponds to unity gain. A value of 0x7FF corresponds to a gain
of 6 dB.
Ringing Oscillator Frequency Coefficient.
Sets ringing generator frequency.
Ringing Oscillator Amplitude Register.
Sets ringing generator signal amplitude.
Ringing Oscillator Initial Phase Register.
Sets initial phase of ringing generator signal.
Pulse Metering Oscillator Attack/Decay Ramp Rate.
Sets pulse metering attack/decay ramp rate.
Pulse Metering Oscillator Amplitude Register.
Sets pulse metering generator signal amplitude.
Pulse Metering Oscillator Frequency Coefficient.
Sets pulse metering generator frequency.
