SLICE_STAT
reserved
Slicer source status.
A 1-bit value to indicate which SPDIF input pin is
selected for the input source. Logic 0 indicates the IEC 60958 input is from
pin SPDIF0. Logic 1 indicates the IEC 60958 input is from pin SPDIF1.
Burst preamble detection.
A 1-bit value to indicate whether burst preamble
words are detected in the SPDIF stream or not. Logic 0 indicates no preamble
words are detected. Logic 1 indicates the burst-payload is detected.
Bit error detection.
A 1-bit value to indicate whether there are bit errors
detected in the SPDIF stream or not. Logic 0 indicates no errors are detected.
Logic 1 indicates bi-phase errors are detected.
SPDIF lock indicator.
A 1-bit value to indicate whether the SPDIF decoder
block is in lock or not. Logic 0 indicates the decoder block is out-of-lock.
Logic 1 indicates the decoder block is in lock.
