    Unable to use interrupts from non-adjacent pins on PSoC 4



      I have 3 signals connected to P3[0], P3[1], P3[4], and I want the three of them to generate a single interrupt.


      PSoC 4 supports this, because the signals are connected to the same port, but PSoC Creator (v4.0) doesn't let me do this, because the signal are not connected to adjacent pins. When I deactivate the "Contiguous" checkbox, the "Spanning" checkbox is automatically activated, which creates an error and I can't do anything about it.


      See the attached screenshots.


      I cannot move the signals anywhere, because the PCB is already produced.


      How can I override this constraint, which is not a PSoC 4 constraint?
