9.7.2.1. Exception Occurs

When an exception occurs, and control transfers to the general exception funnel, it does the following:
  • Switches to the separate exception stack (if enabled)
  • Stores register values onto the stack
  • Determines the type of exception, and passes control to the software exception funnel, the hardware interrupt funnel, or the respective interrupt handlers.
