if 44.1k/48k/32k are detected in the SPDIF channel status bits.
0'b1 => Deemphasis filter is not automatically applied.
[3]
spdif_autodetect
1'b1 => Automatically detect SPDIF input.
1'b0 => Must manually select SPDIF input.
Note: This should only be set if I2S data will not be applied to the pins.
[2]
Fir_length
1'b1 => 2nd stage FIR filter is 28 coefficients in length.
1'b0 => 2nd stage FIR filter is 27 coefficients in length.
[1]
fin_phase_flip
1'b1 => Invert the phase to the DPLL.
1'b0 => Do not invert the phase to the DPLL.
[0]
all_mono
1'b1 => All 8 DAC's are sourced from one source for true mono.
The channel to use as the source is selected by te mono_ch_select register.
1'b0 => Normal 8 channel mode.
Register #18: SPDIF Source
(default = 8’d1)
This registers chooses the SPDIF source. The SABRE
32 Reference has an 8-to-1 multiplexer which
allows up to 8 SPDIF inputs to be connected to the data pins.
