peripherals can access the DSP’s off-chip boot memory
space. After reset, the DSP always starts executing instruc-
tions from the on-chip boot ROM. Depending on the boot
configuration, the boot ROM code can start booting the
DSP from boot memory.

rupts with minimum overhead. The controller implements
an interrupt priority scheme as shown in
tions can use the unassigned slots for software and
peripheral interrupts.
