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. Information about this register is located in Section
page63.
7.4.11: page82. Additional information about EAPD can also be found in Section 7.1.18.3:

Validity: This bit affects the "Validity" flag, bit<28>, transmitted in
each S/PDIF subframe, and enables the S/PDIF transmitter to
maintain connection during error or mute conditions. 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).
1 = Double Rate SPDIF support (always = 0)
SPDIF Sample Rate.
00 - 44.1 KHz Rate
01 - Reserved
10 - 48 KHz Rate (default)
11 - 32 KHz Rate
Generation Level is defined by the IEC standard, or as
appropriate.
Category Code is defined by the IEC standard or as appropriate
by media.
0 = 0 sec Pre-emphasis
1 = Pre-emphasis is 50/15 sec
0 = Copyright not asserted
1 = Copyright is asserted
0 = PCM data
1 = Non-Audio or non-PCM format
0 = Consumer use of the channel
1 = Professional use of the channel
