Field (Bits)
Description
TX_ACTIVE
(14)
When set, this bit enables this queue.
To enable a connection for this queue:
• 1)Assert this bit.
• 2)Add this queue to the ADDQ_FIFO
Register.
To disable a connection on this queue, clear the
TX_ACTIVE bit. This queue is then removed from
the calendar queue the next time a cell would have
been sent. Once this bit is cleared, the associated
queue must not be returned to the add-queue FIFO
until FRAMES_PER_CELL frames have passed by.
If quick reconfiguration is required and the size of
the queue is not going to change (number of
allocated channels), then use SUPPRESS_XMT bit
to pause queue and reconfigure instead of clearing
TX_ACTIVE bit.
When reactivating a previously active queue, be
sure to reinitialize all the registers in the queue table
for that queue.
