    PSoC3 GPIO interrupt configured to rising edge but ISR executed on both the Edges

      Dear developers,

         

                                  I'm getting a strange problem while using one of the GPIO pins of the PSoC 3 (CY8C3866-AXI-040). Even though I have configured the GPIO interrupt to trigger on rising edge only, the interrupt triggers on both the rising as well as the falling edges. The attached project might be referred. the interrupt I'm referring to is the POS_EDGE_IN pin interrupt. What might have gone wrong. Please note that I'm generating interrupt from one of the clock sources of the same IC. Would that be a potential problem.
