Interrupt Sources

Each interrupt is allocated two instructions in the table, so there are 128 table entries for
interrupt handling. Table 4-2 shows the table entry address for each interrupt source.
The DSP56305 initialization program loads the table entry for each interrupt serviced
with two interrupt servicing instructions.
In the DSP56305, not all of the 128 vector addresses are used for specific interrupt
sources. The remaining addresses are reserved. If it is known that certain interrupts will
not be used, those interrupt vector locations may be used for program or data storage.
