BIT FUNCTIONREAD/WRITERESET VALUENAME
D1 EFFCTL 0 R/W Digital Audio Effects Filter
0 => Disable digital audio effects filter
1 => Enable digital audio effects filter
D0 DEEMPF 0 R/W De−emphasis Filter Enable
0 => Disable de−emphasis filter
1 => Enable de−emphasis filter

FUNCTION
D15−D14 DMSVOL 00 R/W DAC Channel Master Volume Control
00 => Left channel and right channel have independent volume controls
01 => Left channel volume control is the programmed value of the right channel volume control.
10 => Right channel volume control is the programmed value of the left channel volume control.
11 => same as 00
D13 REFFS 0 R/W Reference Sampling Rate
Note: This setting controls the coefficients in the de−emphasis filter, the time−constants in AGC,
and internal divider values that generate the clock for the touch screen measurement ADC. If an
Fsref above 48 kHz is being used, then it is recommended to set this to the 48−kHz setting,
otherwise either setting can be used.
0 => Fsref = 48.0 kHz
1 => Fsref = 44.1 kHz
D12 DAXFM 0 R/W Master Transfer Mode
0 => Continuous data transfer mode
1 => 256−s data transfer mode
D11 SLVMS 0 R/W CODEC Master Slave Selection
0 => The TSC2101 is slave codec
1 => The TSC2101 is master codec
D10−D9 0’s R Reserved
D8 ADCOVF 0 R ADC Channel Overflow Flag
0 => ADC channel data is within saturation limits
1 => ADC channel data has exceeded saturation limits.
Note: This flag gets reset after register read.
D7 DALOVF 0 R DAC Left Channel Overflow Flag
0 => DAC left channel data is within saturation limits
1 => DAC left channel data has exceeded saturation limits
Note: This flag gets reset after register read.
D6 DAROVF 0 R DAC Right Channel Overflow Flag
0 => DAC right channel data is within saturation limits
1 => DAC right channel data has exceeded saturation limits
Note: This flag gets reset after register read.
D5−D4 00 R/W Reserved.
D3 CLPST 0 R/W MIC AGC Clip Stepping Disable
0 => Disabled
1 => Enabled
Note: Valid only when AGC is selected for the Headset/Aux or Handset input.
