How to trigger the interrupt for SPI in MK60FN1M0VLQ12 controller ?

We have made PTE2 (Pin3 of Controller MK60FN1M0VLQ12) as interrupt pin for ADXL peripheral connected via SPI. We had configured it to detect interrupt on rising edge. We are seeing Pin 3 going High. In Vector.c we had configured the interrupt function.

We are not getting the interrupt even though Pin 3 is high (checked via oscilloscope). We checked ISR function is not hitting by putting a breakpoint in the function.

 

What could be the issue? Why ISR is not hitting even though in oscilloscope we see pin going HIGH?

 

For your information, i have attached the screeshots of Vector table, ISR for interrupt and the Interrupt signal captured from the Oscilloscope.

 

Note: we have checked PTE2 pin by polling method, so it is not continuously high.
