64 / 95 page  STAC9752/9753 TWO-CHANNEL, 20-BIT, AC’97 2.3 CODECS WITH HEADPHONE DRIVE, SPDIF OUTPUT MICROPHONE & JACK SENSING IDT™ 64 STAC9752/9753 REV 3.3 1206 TWO-CHANNEL, 20-BIT, AC’97 2.3 CODECS WITH HEADPHONE DRIVE, SPDIF OUTPUT MICROPHONE & JACK SENSING 8.1.24. SPDIF Control (3Ah) Default: 2000h 8.2. General Purpose Input & Outputs 8.2.1. EAPD EAPD can act as a GPIO, but is unaffected by the following registers. To use EAPD as a GPIO, use Register 74h, the EAPD Access Register located in Section 8.4.11: page77. Additional information about EAPD can also be found in Section 8.1.18.3: page 59.

Subframe bit[28] = 0 indicates that data is valid for conversion at the receiver, 1 indicates invalid data (not suitable for conversion at the receiver). If “V” = 1, then each S/PDIF subframe (Left & Right) should have bit[28] “Validity” flag = 1 or set based on the assertion or de-assertion of the AC'97 “VFORCE” bit within the Extended Audio Status and Control Register (D15, register 2Ah). 14 0 Read Only DRS 1 = Double Rate SPDIF support (always = 0) 13:12 10 Read & Write SPSR[1,0] SPDIF Sample Rate. 00 - 44.1 KHz Rate 01 - Reserved 10 - 48 KHz Rate (default) 11 - 32 KHz Rate 11 0 Read & Write L Generation Level is defined by the IEC standard, or as appropriate. 10:4 0 Read & Write CC[6, 0] Category Code is defined by the IEC standard or as appropriate by media. 3 0 Read & Write PRE 0 = Pre-emphasis = 0 µsec 1 = Pre-emphasis = 50/15 µsec 2 0 Read & Write COPY 0 = Copyright not asserted 1 = Copyright is asserted 1 0 Read & Write /AUDIO 0 = PCM data 1 = Non-Audio or non-PCM format 0 0 Read & Write PRO 0 = Consumer use of the channel 1 = Professional use of the channel |
