4.3.11.2.2. Synchronous Exception Handling

Unlike interrupts, exceptions are not supported with configurable exception level, priority and hardware vectoring. Here are related descriptions:

  • Exception Level—They are serviced with the same interrupt level as the instruction that raised the exception.
  • Exception Priority—Refer to Table: Exception Priority in Decreasing Priority Order. Note that exception priority is unrelated to the interrupt priorities, and it is enforced upon multiple exceptions only.
  • Hardware Vectoring—Not supported. The Nios V processor handles exception similar to Software-Vectored Interrupt Handling. Refer to Software-Vectored Interrupt Handling for more information.
