    Hi shankar hiregadad,


    ISTP is one of the control registers of C674x's CPU. When you include C6x.h ( usually located at "C:\ti\ccsv6\tools\compiler\c6000_7.4.12\include") you will be able to access.In C6x.h you will see the C type declarations of these control registers...

    For more info on Control registers, please visit : www.ti.com/.../sprufe8b.pdf

    In "intvecs.asm" the "intcVectorTable" is defined. It is located at "rcsl_examples\evmomapl137\dsp_examples\uart\uart_interrupt_loopback_dspl137\src"
