Hello David,
Thank you for responding.
I am using processor expert in KDS. The processor I am using is K10DX256VLH7. I have found the method to specify user supplied vector.
For others who may want to know how to do this:
Right click on CPU tile in Processor display, Select Add Component/Template -> InterruptVector.
This adds component to specify user supplied vector function name for most interrupt types. Priority. can also be set at the same time.
Thanks Again.
