   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
   vectors are predefined. Remaining software interrupts can be added here
   as well.
   NOTE: If software interrupts 0 to 7 are defined here, this might 
   conflict with the reset vector in the start-up file.
