The C64x+ 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 5-18
. Also, the interrupt
controller controls the generation of the CPU exception, NMI, and emulation interrupts and the generation
of AEG events.
Table 5-19
summarizes the C64x+ interrupt controller registers and memory locations. For
more details on DSP interrupt control, see the
Documentation Support
section for the DSP Subsystem
User's Guide.
