hello! today i am first time here and hope someone will help me ;-) it is even the first tim using interrupthandlers, so i am still unexperienced ;-( i tryed to edit a small program, which flashes a LED in defined cycles, but the ICC12 compiler does not translate the code to a *.S19 file. the problemlien is marked by many: !!!!!!!!!!!!! what is wrong in my program? Thanx!!! Stefan here the program: #define RTICTL _P(0x14) #define RTIFREG _P(0x15) #include <HC12.H> int x; int counter; void delay(x)//x=1 entspricht ca. 0.0016ms { while (x!=0) { x--; } } #pragma interrupt_handler RTIhandler void RTIhandler (void) { int a; RTIFREG &=~ 0x80; if (counter < 10) { counter++; } else { counter=0; a0; while(a!=0)//led flashes { PORTT|=0x08; delay(32000); //fHz PORTT&=~0x08; delay(32000); a--; } } } //vectoraddress for RTIhandler #pragma abs_address: 0xfff0 void (*RTI_vector[])()={RTIhandler};//in this line the compiler says:!!!!!!!!!!!!!!!!!!!!!!!!!!!!! //'declaring a function without prototype may cause errors' !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! #pragma end_abs_address void main(void) { DDRT=0xFF; asm("CLI \n"); RTICTL=0x07; //Adresse 0014 / t4.072ms @ 4MHz counter=0; } /********* vectors.c ***********************/ /* As is, all interrupts except reset jumps to 0xffff, which is most * likely not going to useful.

Try RTIFREG=0x80 or RTIFREG&=0x80 if last compiles to BCLR RTIFREG,#0x7F. Your code generates BCLR RTIFREG,#0x80 and doesn't clear RTIFLG!
