Setting Up TMS320C2xx Interrupts in Assembler or C
Texas InstrumentsTypically interrupts are generated by devices that need to give or take data from the Texas Instruments (TI) (tm) TMS320C2xx for example analog-to-digital (A/D) and digital-to-analog (D/A) converters or other processors. When the C2xx recognizes an interrupt signal it suspends execution of the code specific to the particular interrupt event (Interrupt Subroutine).The C2xx family supports t
