Interrupt
This field defines the interrupt level for the adapter to use when reporting
command completion. You can also denote the resultant interrupt acknowledge
ID that the adapter will place on the data bus in response to the host. The
Interrupt field of the Start Command List Parameter Block uses these bit-
meanings:
Status/ID Interrupt Status/ID - This byte denotes the value the adapter will
provide to identify the interrupt being acknowledged by the Host.
INT Interrupt Level - You may elect to use any one of the following levels
for adapter interrupt:
000 — Interrupt disabled
001 — Interrupt level 1
010 — Interrupt level 2
011 — Interrupt level 3
100 — Interrupt level 4
101 — Interrupt level 5
110 — Interrupt level 6
111 — Interrupt level 7
Note
An Error Code of 11H
will be returned in the
Status Block if you
attempt to start an
already started
Command List.
