SETTING UP TMS320 DSP INTERRUPTS IN 'C'

Four steps are required to set the TMS320 DSP interrupts: create a interrupt service routine, initialize the vector table and set the memory map, enable the interrupts in the CPU, and enable the interrupt sources. This document shows how to set the interrupts in C, C callable assembly, or in-line C. Sample C code segments are provided. The appendix gives complete examples for setting interrupt vectors in C for the 16-bit fixed point TMS320C25, TMS320C26, and TMS320C50 processors and the 32-bit floating point TMS320C30, TMS320C31, and TMS320C40 processors.
