Enable S/PDIF to I2S Output Register (Address 0xE241)
This MP output is controlled by setting three bits in
Register 0xE241:

Bit 0 switches Group 1 on and off.
Bit 1 switches Group 2 on and off.
Bit 2 switches between I2S and TDM modes.
When S/PDIF to I2S mode is active, the pins described in Table 51
are used.
When TDM mode is active, Slot 0 and Slot 4 contain the audio
data, and Slot 1 contains the streamed block start, channel status,
user data, and validity bits (see Table 63). The bits are streamed
in real time and are synchronized to the audio data. Only the
seven MSBs of Slot 1 are used, as shown in Table 63. The corre-
sponding TDM format is shown in more detail in Figure 54.
Table 63. Function of Decoded Bits in Figure 54
The S/PDIF receiver can be set to send the stereo audio stream
and the auxiliary S/PDIF bits in I2S or TDM format on eight of
the 12 MP pins. The eight outputs are divided into two groups:
Group 1 converts S/PDIF to I2S (LRCLK, BCLK, and SDATA
signals), and Group 2 decodes the channel status and user data
bits (virtual LRCLK, user data, channel status, validity bit, and
block start signal).
