Functional Overview
3.5 Interrupts
Vector-relative locations and priorities for all internal and external interrupts are shown in Table 3−21. The
locations of the interrupt vectors are defined as an offset from the location defined in the interrupt vector
pointers (IVPD and IVPH). For more detailed information about the interrupt vector pointers and interrupts,
see the TMS320C55x DSP CPU Reference Guide (literature number SPRU371).
