6.7 DSP Interrupts

The C674x DSP interrupt controller combines device events into 12 prioritized interrupts. The source for each of the 12 CPU interrupts is user programmable and is listed in Table 6-7. Also, the interrupt controller controls the generation of the CPU exception, NMI, and emulation interrupts. Table 6-8 summarizes the C674x interrupt controller registers and memory locations.
