135 / 407 page  CP3SP33 www.ti.com SNOSCW5 – MAY 2013 ADC2STATUS The ADC2 Status bit indicates whether ADC2 is enabled. If ADC2 is enabled, its clock must not be disabled. 0 – ADC2 disabled. 1 – ADC2 enabled. 20.10.4 Codec DSP Set-Up Register (TCDCDSP) The TCDCDSP register is a 16-bit, read/write register that configures some of the DSP portions of the module. After reset, this register is cleared to 0000h. 15 14 13 12 9 8 7 5 4 3 2 1 0 CUST ADC2 ADC1 DAC DAC Reserved STCLPR STCLPL SIDETONEATTEN CLKPH DIGMICGAIN COMP DITOFF DITOFF DITOFF DITON DACDITON The DAC Dither On bit enables dithering the output, without regard to the audio content. 0 – Dithering may be on or off. 1 – Dithering always on. DACDITOFF The DAC Dither Off bit disables dithering the output, without regard to the audio content. If set, this bit overrides the DACDITON bit. 0 – Dithering may be on or off. 1 – Dithering always off. ADC1DITON The ADC1 Dither Off bit disables dithering the ADC1 ASDM input. 0 – Dithering may be on or off. 1 – Dithering always off. ADC2DITON The ADC2 Dither Off bit disables dithering the ADC2 ASDM input. 0 – Dithering may be on or off. 1 – Dithering always off. CUSTCOMP The CUSTCOMP bit selects between default compensation filter coefficients and custom values in the TCDCCOMP0, TCDCCOMP1, and TCDCCOMP2 registers. Default values vary with the over-sampling rate to keep the reconstruction filter output flat up to 20kHz. 0 – Default coefficients are used. 1 – Custom coefficients are used. DIGMICGAIN The DIGMICGAIN field selects a scaling factor for the DIGMIC1 input data. It can be used to provide extra gain for small analog signals when the microphone pre-amplifier gain is not sufficient. It is controllable in 2 dB steps between 0 dB and 14 dB.
