Description

192 kHz Recovered Sample Rate - Measured
audio sample rate of incoming S/PDIF data. A
‘1’b indicates a 192 kHz sample rate.
96 kHz Recovered Sample Rate - Measured
audio sample rate of incoming S/PDIF data. A
‘1’b indicates a 96 kHz sample rate.
48 kHz Recovered Sample Rate - Measured
audio sample rate of incoming S/PDIF data. A
‘1’b indicates a 48 kHz sample rate.
44.1 kHz Recovered Sample Rate - Measured
audio sample rate of incoming S/PDIF data.A
‘1’b indicates a 44.1 kHz sample rate.
32 kHz Recovered Sample Rate - Measured
audio sample rate of incoming S/PDIF data. A
‘1’b indicates a 32 kHz sample rate.
CCRC - Channel Status Block Cyclic Redun-
dancy Check bit. Updated on CS block bound-
aries, valid only in Pro mode. This bit will go
high on occurrence of the error, and will
stay high until the register is read. Reading
the register resets this bit to 0, unless the
error condition is still true.
0 - No error.
1 - Error.
BIP - Bi-phase error bit. Updated on sub-frame
boundaries. This bit will go high on occur-
rence of the error, and will stay high until the
register is read. Reading the register resets
this bit to 0, unless the error condition is still
true.
0 - No error.
1 - Bi-phase error. This indicates an error in the
received bi-phase coding.
PAR - Parity bit. Updated on sub-frame bound-
aries. This bit will go high on occurrence of
the error, and will stay high until the register
is read. Reading the register resets this bit
to 0, unless the error condition is still true.
0 - No error.
1 - Parity error.
SPUL - S/PDIF Receiver Unlock Indicator
1 - The receiver is unlocked or has transition-ed
from lock to unlock since the last read.
0 - The receiver is locked and has not transition-
ed from lock to unlock since the last read.
SPL - S/PDIF Receiver Lock Indicator
1 - The receiver is locked or has transition-ed
from unlock to lock since the last read.
0 - The receiver is unlocked and has not transi-
tion-ed from unlock to lock since the last read.
