Interrupt Queue Length
This bit field assigns a interrupt queue length to the eight channel
interrupt queues. To set the interrupt queue length of a specific queue,
system software must first program IQL. Afterwards the value is released
by selecting the associated queue via bit field IQIA.Q and setting of bit
IQIA.SIQL. IQL specifies the interrupt queue length L (number of
DWORDs) in the shared memory with
L=(IQL+1)*16 (maximum of 4092 DWORDs).
Note: IQL = 255 equals a queue length of 1 DWORD.
Whenever the length of a particular interrupt queue is modified, the next
interrupt vector written to that queue is stored in the first location of the
queue.
