Description
QUEUE_H
(12:8)
Five LSBs of the queue index associated with this DS0. The three MSBs
are implicitly those of the line number.
Offset = (channel - 1) ÷ 2 + line × 16.
For unstructured lines, set to the receive queue number mod 32.
RX_COND_L
(7:6)
Determines the type of data to be played out:
NOTE: Options “00”, “01”, and “11” are executed only when the
queue is in an underrun or resume state.
00b When the queue is in underrun, read signaling for this channel
from multiframe 0 and the data for this channel from the R_
COND_DATA table (refer to section 7.8.8 “R_COND_
DATA” on page 151).
01b When the queue is in underrun, read signaling for this channel
from multiframe 0 and play out pseudorandom data, which is
inserted data from R_COND_DATA, with the MSB con-
trolled by the pseudorandom number algorithm x18 + x7 + 1
(not valid for UDF-HS).
10b Read signaling for this channel from the R_COND_SIG table
(refer to section 7.8.7 “R_COND_SIG” on page 150) and the
data for this channel from the R_COND_DATA table.
11b When the queue is in underrun, read the signaling from multi-
frame 0 and play out the contents of the buffer.
Not used
(5)
Write with a 0 to maintain future software compatibility.
QUEUE_L
(4:0)
Five LSBs of the queue index associated with this DS0. The three MSBs
are implicitly those of the line number.
Offset = channel ÷ 2 + line × 16.
