   to set all interrupt priorities in static applications. If this file
   contains assignments to dedicated resources, verify  that the
   appropriate controller is used.

   NOTE: value 7 disables the interrupt and value 0 sets highest priority.
   NOTE: Two resource interrupts always share one ICR register.

   Vector definiton

   Use following statements to define vectors. All resource related

   NOTE: If software interrupts 0 to 7 are defined here, this might 
   conflict with the reset vector in the start-up file.
