6.15.6.1 S/PDIF RX/TX Interface Status (CIR = 0000h)
Bits Type Default Description
15:10 Read Only 0 Reserved
9 Read Only 0b
192 kHz Recovered Sample Rate - Measured
audio sample rate of incoming S/PDIF data. A
‘1’b indicates a 192 kHz sample rate.
8 Read Only 0b
96 kHz Recovered Sample Rate - Measured
audio sample rate of incoming S/PDIF data. A
‘1’b indicates a 96 kHz sample rate.
7 Read Only 0b
48 kHz Recovered Sample Rate - Measured
audio sample rate of incoming S/PDIF data. A
‘1’b indicates a 48 kHz sample rate.
6 Read Only 0b
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.
5 Read Only 0b
32 kHz Recovered Sample Rate - Measured
audio sample rate of incoming S/PDIF data. A
‘1’b indicates a 32 kHz sample rate.
4 Read Only 0b
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.
3 Read Only 0b
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.
2 Read Only 0b
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.
1 Read Only 0b
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.
0 Read Only 0b
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.
