The tables are accessed by the microcontroller via control registers, data transfer
registers and mask registers. While the control registers
“WAR” on Page 309
registers are dedicated or shared among some tables. Data transfer registers are always
dedicated to the specific table.
3.5.2
The basic function of the LCI table is assigning the connection (identified by the LCI) to
one out of 8192 queues per direction. Single connections can be assigned to a dedicated
queue (per VC queueing) or multiple connections might be assigned to the same queue.

3.5.3
The basic function of the QCT table is to determine queue specific parameters and to
assign the queue to dedicated resources (Traffic Class, Scheduler Block, Merge Group).
“Queue Configuration Table Transfer Registers” on Page 211
3.5.4
The function of the QPT table is to configure the weight factor (in case a queue is
assigned to the WFQ scheduler) and the peak cell rate value (in case the peak cell rate
shaper is enabled).

3.5.5
The function of the TCT table is to configure the buffer management behavior of up to
16 traffic classes.

3.5.6
The function of the SBOC table (for 2*128 scheduler blocks) is to maintain the buffer
filling levels associated with the dedicated scheduler.

details.
3.5.7
The function of the SCT table (for 2*128 scheduler blocks) is to determine the integer
part (SCTI) and fractional part (SCTF) of the scheduler block output rates as well as the
UTOPIA port number the scheduler is assigned to.
