9.2.2.2. How the Software Works

The trap handling system implementation is one of many possible implementations of a trap handling system for the Nios® V processor. Some features of the HAL trap handling system are constrained by the Nios® V processor hardware, while others provide generally useful services.

You can take advantage of the HAL trap handling system without a complete understanding of the HAL implementation.

For more information about how to install ISRs using the HAL API, refer to the Interrupt Service Routines and Exception Handler.
