    Bug in CYLIB.h

    user_1377889

      When using CyIntSetPriority() the value is checked against a #defined constant named CY_MIN_PRIORITY near line 319 in CyLib.h. CY_MIN_PRIORITY has the value 3, but it should be 7. The description of CyIntSetPriority()  in "System Reference Guide" shows valid priority ranges from 0 to 7 (which is quite logical).

          ... or is that an error in the documentation?

            The problem is in the documentation. The documentation was correct, but we missed updating this for changes that occured with PSoC 4.

               

            PSoC 3 and 5LP can support priorities from 0 to 7 (0 is the highest), but PSoC 4 only supports 0 to 3.  This is because of the Cortex-M0 on the PSoC 4 versus the M3 on the PSoC 5LP.  You didn't say that you were using PSoC 4, but I checked the generated code for both 4 and 5LP and they are different and correct.

               

            Thanks for reporting the problem.

              Yes, since I slept over that issue it came to my mind that there was something different between PSoC5 and PSoC4. I agree that something has got forgotten within the documentation of the System Reference Guide.
