T_CHANNEL_LEFT(15:0) Word Format (10H)
After initialization this word is read only. The word is maintained by TALP.
Field (Bits)
Description
T_CHANNEL_LEFT
(15:0)
Initialize to the same value as
T_CHAN_ALLOC(15:0).
T_CHANNEL_LEFT(31:16) Word Format (11H)
After initialization this word is read only. The word is maintained by TALP.
Field (Bits)
Description
T_CHANNEL_LEFT
(31:16)
Initialize to the same value as
T_CHAN_ALLOC(31:16).
TRANSMIT_CONFIG Word Format (12H)
This word is maintained by the microprocessor. Note: in UDF-HS mode, TALP
reads this word only once, before it generates the first cell of the connection; as
a result, any writes to this word after TALP generates the first cell will have no
affect.
Field (Bits)
Description
SUPPRESS_XMT
(15)
Set to 1 to suppress the generation of cells for this
queue. Cells are scheduled but not transmitted.
Note that this bit is invalid in UDF-HS mode. A
UDF-HS queue needs to be stopped by clearing
the TX_ACTIVE bit and restarted by adding the
queue.
LOOPBACK_ENABLE
(14)
Set to 1 to loopback cell to receive side. Set
VPI/VCI to corresponding receive queue number.
Note to maximize throughput, this register is only
read once in UDF-HS mode, when building the first
cell. Therefore if loopback is desired for UDF-HS
mode, this bit must be set first and cannot be
changed after the queue is already running.
