Core Configuration
Interrupt Sources and Priorities
The DSP56309 initialization program loads the table entry for each interrupt serviced
with two interrupt servicing instructions.
In the DSP56309, only 46 of the 128 vector addresses are used for specific interrupt
sources. The remaining 82 are reserved. If you know that certain interrupts will not be
used, those interrupt vector locations can be used for program or data storage.
