CCS/TMS320F28335: ENIT and ERTM

Tool/software: Code Composer Studio

Hello,

                 I would like to know what is the difference between EINT and ERTM. EINT is to enable global interrupts and ERTM for real time interrupts. Isn't the interrupts supposed to be real time always? Any help is greatly appreciated!

Thanks,

Akhil

    Hi Akhil,

    EINT is equivalent to "clrc INTM" instruction which is required to globally enables all maskable CPU interrupts.
    ERTM is equivalent t0 "clrc DBGM" instruction which is required to allow real time access to emulator in order to access memory & registers.

    Refer to C28x cpu guide for more details on this.

    Thanks
