Real time interrupt problem

hello.

Recently I'm making a embedded module using a real time interrupt.

Problem is if I call a real time service routine, main function doesn't work any more. I mean, the code after the code which can enable a real time interrupt can't be executed.

This is my code.

//// real time service routine ///

#pragma CODE_SEG __NEAR_SEG NON_BANKED
interrupt void RTI_ISR(void){
main_routine();
}

// function//

void main_routine(void) { functions();}

// main function //

void main{

some codes;

EnableInterrupts;

codes that don't work any more;

}

I think routine is working well but only that codes have a trouble. what's wrong with my code?

Hi Kayji,

I suspect that you are not clearing the real-time interrupt-flag, and therefore executing the ISR repeatably.

Are you writing a one to RTIACK?
