8 Interrupt Handling

8.1.Overview

Each ‘C6x has four interrupt pins which are configurable as either leading or falling edge-triggered interrupts. For the Monaco board, all ‘C6x interrupts are configured as rising edge-triggered interrupts. The /NMI interrupts for the ‘C6x DSPs are not used; they are tied high.

The following block diagram shows how interrupts are routed to these pins on the

Monaco board.
