Queue status. Indicates the current condition of queue 1 and queue 2. The two most
significant bits are associated primarily with queue 1, and the remaining two bits are
associated with queue 2. Because the priority scheme between the two queues
causes the status to be interlinked, the status bits must be considered as one 4-bit
field.
queue 1 and queue 2.
The queue status field is affected by QADC stop mode. Because all of the analog logic
and control registers are reset, the queue status field is reset to queue 1 idle, queue
2 idle.
During debug mode, the queue status field is not modified. The queue status field
retains the status it held prior to freezing. As a result, the queue status can show
queue 1 active, queue 2 idle, even though neither queue is being executed during
freeze.
Command word pointer. Denotes which CCW is executing at present or was last
completed. CWP is a read-only field with a valid range of 0 to 63; write operations have
no effect.
During stop mode, CWP is reset to 0 because the control registers and the analog
logic are reset. When debug mode is entered, CWP is not changed; it points to the last
executed CCW.
