D15
KCLEN
R/W
0
Keyclick Enable
0 => Keyclick disabled
1 => Keyclick enabled
Note: This bit is automatically cleared after giving out the keyclick signal length equal to the
programmed value.

Keyclick Amplitude Control
000 => Lowest amplitude
100 => Medium amplitude
111 => Highest amplitude
D11
APGASS
R/W
0
ADC Channel PGA Soft-Stepping Control
0 => 0.5dB change every ADWS
1 => 0.5dB change every 2 ADWS
Note: When AGC is enabled, this bit is read only. The read values indicate the following
0 => signal power greater than noise threshold
1 => signal power is less than noise threshold
D10D8

Keyclick Frequency
000 => 62.5 Hz
001 => 125 Hz
010 => 250 Hz
011 => 500 Hz
100 => 1 kHz
101 => 2 kHz
110 => 4 kHz
111 => 8 kHz

0001
Keyclick Length
0000 => 2 periods key click
0001 => 4 periods key click
0010 => 6 periods key click
1110 => 30 periods key click
1111 => 32 periods key click
D3
DLGAF
R
0
DAC Left Channel PGA Flag ( Read Only )
0 => Gain applied /= PGA register setting
1 => Gain applied = PGA register setting
Note: This flag indicates when the soft-stepping for DAC left channel is completed
D2
DRGAF
R
0
DAC Right Channel PGA Flag ( Read Only )
0 => Gain applied /= PGA register setting
1 => Gain applied = PGA register setting
Note: This flag indicates when the soft-stepping for DAC right channel is completed
D1
DASTC
R/W
0
DAC Channel PGA Soft-Stepping Control
0 => 0.5dB change every LRCK
1 => 0.5dB change every 2 LRCK
D0
ADGAF
R
0
ADC Channel PGA Flag ( Read Only )
1 => Gain applied = PGA register setting
0 => Gain applied /= PGA register setting
Note: This flag indicates when the soft-stepping for ADC channel is completed. When AGC is
enabled the read value of this bit indicates the following:
0 => AGC is not saturated.
1 => AGC is saturated.
