21 / 61 page  DSD1796 SLES101A – DECEMBER 2003 – REVISED NOVEMBER 2006 www.ti.com 21 MODE CONTROL REGISTERS User-Programmable Mode Controls The DSD1796 includes a number of user-programmable functions which are accessed via mode control registers. The registers are programmed using the serial control interface, which is previously desribed in the SERIAL CONTROL INTERFACE section of this data sheet. Table 2 lists the available mode control functions, along with their default reset conditions and associated register index. Table 2. User-Programmable Function Controls FUNCTION DEFAULT REGISTER BIT PCM DSD DF BYPASS Digital attenuation control 0 dB to –120 dB and mute, 0.5 dB step 0 dB Register 16 Register 17 ATL[7:0] (for L-ch) ATR[7:0] (for R-ch) yes Attenuation load control—Disabled, enabled Attenuation disabled Register 18 ATLD yes Input audio data format selection 16-, 20-, 24-bit standard (right-justified) format 24-bit MSB-first left-justified format 16-/24-bit I2S format 24-bit I2S format Register 18 FMT[2:0] yes yes Sampling rate selection for de-emphasis Disabled,44.1 kHz, 48 kHz, 32 kHz De-emphasis disabled Register 18 DMF[1:0] yes yes(1) De-emphasis control—Disabled, enabled De-emphasis disabled Register 18 DME yes Soft mute control—Mute disabled, enabled Mute disabled Register 18 MUTE yes Output phase reversal—Normal, reverse Normal Register 19 REV yes yes yes Attenuation speed selection ×1 fS, ×(1/2)fS, ×(1/4)fS, ×(1/8)fS ×1 fS Register 19 ATS[1:0] yes DAC operation control—Enabled, disabled DAC operation enabled Register 19 OPE yes yes yes Zero flag pin operation control DSD data input, zero flag output DSD data input Register 19 ZOE yes yes Stereo DF bypass mode select Monaural, stereo Monaural Register 19 DFMS yes Digital filter rolloff selection Sharp rolloff, slow rolloff Sharp rolloff Register 19 FLT yes Infinite zero mute control Disabled, enabled Disabled Register 19 INZD yes yes System reset control Reset operation , normal operation Normal operation Register 20 SRST yes yes yes DSD interface mode control DSD enabled, disabled Disabled Register 20 DSD yes yes Digital-filter bypass control DF enabled, DF bypass DF enabled Register 20 DFTH yes yes Monaural mode selection Stereo, monaural Stereo Register 20 MONO yes yes yes Channel selection for monaural mode data L-channel, R-channel L-channel Register 20 CHSL yes yes yes Delta-sigma oversampling rate selection ×64 fS, ×128 fS, ×32 fS ×64 fS Register 20 OS[1:0] yes yes(2) yes PCM zero output enable Enabled Register 21 PCMZ yes yes DSD zero output enable Disabled Register 21 DZ[1:0] yes FUNCTION AVAILABLE ONLY FOR READ Zero detection flag Not zero, zero detected Not zero = 0 Zero detected = 1 Register 22 ZFGL (for L-ch) ZFGR (for R-ch) yes yes yes Device ID (at TDMCA) – Register 23 ID[4:0] yes (1) When in DSD mode, DMF[1:0] is defined as DSD filter (analog FIR) performance selection.
