8 LINK CES/DBCES AAL1 SAR
Field (Bits)
Description
AAL0_MODE_ENABLE Set to 1 to build AAL0 cells instead of AAL1. Use
QUEUE_CREDITS=x0180,
AVG_SUB_VALU=x0180, and
(13)
BYTES_PER_CELL=x30 for full AAL0 cells.
COND_MODE
(12:11))
Selects the conditioning mode with the following
encoding:
00 Both signaling and data are conditioned
01 Only signaling is conditioned
10 Only data is conditioned
11 reserved
The chosen mode takes effect when the TX_COND
bit is set in the QUEUE_CONFIG memory register.
If data is conditioned the T_COND_CELL_CNT
counter will increment. If only signaling is
conditioned the T_CELL_CNT will increment as
normal.
DBCES_ENABLE
Set to 1 to enable DBCES functionality.
(10)
IDLE_DET_ENABLE
(9)
Set to 1 to enable idle detection in non-DBCES
mode. When in this mode a queue which has all
idle channels will have its transmission of cells
suppressed. Any suppressed cell will cause the
T_SUPPRESS_CNT to be incremented.
Not used
(8:0)
Write with a 0 to maintain future software
compatibility.
CSD BYTES LEFT Word Format (17H)
This word is initialized by the microprocessor and then maintained by CSD. This
register is only used for DBCES. This register should not be written after queue
is started.
Field (Bits)
Description
BITMASK_CELL
(15)
Set to 1 to build a cell with a bitmask. This bit must
be initialized to 1 when starting a DBCES queue.
