+          Reads on the Blackfin are speculative. In Blackfin terms, this means
+          they can be interrupted at any time (even after they have been issued
+          on to the external bus), and re-issued after the interrupt occurs.
+          For memory - this is not a big deal, since memory does not change if
+          it sees a read.
+
+          If a FIFO is sitting on the end of the read, it will see two reads,
+          when the core only sees one since the FIFO receives both the read
+          which is cancelled (and not delivered to the core) and the one which
+          is re-issued (which is delivered to the core).
+
+          To solve this, interrupts are turned off before reads occur to
+          I/O space. This option controls which the overhead/latency of
+          controlling interrupts during this time
+           "n" turns interrupts off every read
+                (higher overhead, but lower interrupt latency)
+           "y" turns interrupts off every loop
+                (low overhead, but longer interrupt latency)
+
+          default behavior is to leave this set to on (type "Y"). If you are experiencing
+          interrupt latency issues, it is safe and OK to turn this off.
