8.2.2.1. Using General Exception Funnels

The funnel code receives control from the general exception vector. The funnel performs tasks such as saving the stack pointer, saving registers and calling RTOS context-switch routines, and transfers control to the handler. When the handler returns, the funnel code performs tasks such as calling RTOS process-dispatch routines and restoring registers, and transfers control to the appropriate foreground task.
