Reply Responses
The first word returned is always EXPECT, the number of
expected status words, followed by the status words followed by
the interpreter status ISTATUS.
AC3 Status Reply
AC3STATR
This reply is a response to the STAT command during the AC3
function operation.
PCMPROL Status Reply
PCMPROLR
This reply is a response to the STAT command during the PCM
or Pro Logic function operation. The status fields are the same
as for AC3STATR except:
STATUS
Global Status
of operation in progress: 0 = No errors, 1
= Updated status information is not yet available (a new
command has been received and is being processed),
2 = Operation error (see Status word 2 for details).
RST
Run Status:
0 = Running, 1 = Stopped, 2 & 3 =
Reserved.
AC3DST
AC-3 Decode Status
returned by routine: 0 = No errors,
1 = Input status nonzero, last output block was repeat-
ed, 2 = Input status nonzero, outputs were muted, 3 =
Unsupported bitstream identification revision, 4 =
Unsupported number of channels in input stream, 5 =
Unsupported number of input streams.
AC3IST
AC-3 Frame Information Status
returned by routine:
0 = No errors, 1 = Invalid frame sync, 2 = Invalid sample
rate, 3 = Invalid data rate, 4-6 = Reserved, 7 = Input
underflow.
DIFT[15:0]
Difference Time.
Signed difference between PTC and
STC in units of the 90-kHz clock. For packetized inputs.
SR
Sample Rate:
0 = 48 kHz, 1 = 44.1 kHz, 2 = 32 kHz.
IDR
Input Data Rate
