I wrote simple demostration program.
When I start GO debug function, debbuger stops ! Why?

Please advice !

Program:

#include "defs.h" //BEGIN,END,TRUE,FALSE...
#include "89C51RD2.h" //SFR

void IE0_Irq(); //IE0 interrupt proc

bit bdata IsIE0 = FALSE;

/* Ini Program
IE0 interrupt on 200mS

signal void HP(void) {
PORT3 |= 0x04;//H
swatch(10);
while (1) {
PORT3 &= ~0x04;//H->L = IE0 interrupt
swatch(0.1); //
PORT3 |= 0x04; //H
swatch(0.1); //
}//while
}//proc

*/

void main () using 0
BEGIN //[
while (TRUE){ //After GO stops here
if (IsIE0) { //Brekpoint : I'm waiting to stop on
//this line. (It happens after few GO!)
IsIE0 = FALSE;
}
}//Konec while TRUE
END //]

void IE0_Irq() interrupt IE0_VECTOR using 1
BEGIN //[
IsIE0 = TRUE;
END //]
