59 / 95 page  TSC2101 SLAS392D− JUNE 2003 − REVISED MAY 2005 www.ti.com 59 REGISTER 04H: Audio Control 2 BIT NAME RESET VALUE READ/ WRITE FUNCTION D15 KCLEN 0 R/W 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. D14−D12 KCLAC 100 R/W Keyclick Amplitude Control 000 => Lowest Amplitude …. 100 => Medium Amplitude …. 111 => Highest Amplitude D11 APGASS 0 R/W Headset/Aux or Handset PGA Soft−stepping control 0 => 0.5 dB change every WCLK or ADWS 1 => 0.5 dB change every 2 WCLK or 2 ADWS When AGC is enabled for Headset/Aux or Handset, this bit is read only and acts as Noise Threshold Flag. The read value indicates the following 0 => signal power greater than noise threshold 1 => signal power is less than noise threshold D10−D8 KCLFRQ 100 R/W 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 D7−D4 KCLLN 0001 R/W Keyclick Length 0000 => 2 periods key click 0001 => 4 periods key click 0010 => 6 periods key click 0011 => 8 periods key click 0100 => 10 periods key click 0101 => 12 periods key click 0110 => 14 periods key click 0111 => 16 periods key click 1000 => 18 periods key click 1001 => 20 periods key click 1010 => 22 periods key click 1011 => 24 periods key click 1100 => 26 periods key click 1101 => 28 periods key click 1110 => 30 periods key click 1111 => 32 periods key click D3 DLGAF 0 R DAC Left Channel PGA Flag 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 0 R DAC Right Channel PGA Flag 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 |
