It is a bit difficult to make a guess right into the blue, I'm afraid we need some more information to help you out of this.
Best would be to post the complete project here, use Creator's "Create Workspace Bundle" and upload the resulting archive. DO NOT USE CHROME when uploading, some bug preventst the file from getting into the forum.
thanks for reply.
I am posting my code.
I am using two external port pin interrupts.
controller.c has sleep mode routines.
application.c has my application where RF module sends signal as any of the two port pin interrupts are occured
main.c has states i.e from sleep to wakeup due to PICU, send signal using RF and then again back to sleep
please use psoc creator 2.2 to open the project

I cannot see a flaw in your code at first sight. Only the setting of the isrs is "derived" and ought to be changed to "level" as I understood the documentation.
I would try to reduce the project to the smallest program just showing the error.
