Dear all:
I'm write a simply program to test C for NXP. I only open timer 1 to use,Then i set a breakpoint in the interrupt, But the interrupt never be break,I don't why? Can anyone tell me why? //************************************************ void interrupt(void) { if(Timer_bit) { if(Timer_bit) { Timer_bit=0; TimerH=(65536-time1_base)/256; TtimerL=(65536-time1_base)%256;
if(!(--A)) A=10; } } } // void main() { initial(); while(1) { ClearwatchGod(); r_cnt++; } } //
To use any tool effectively, you have to follow its instructions!
The instructions for posting source code on this forum are clearly stated:

If you missed that one, maybe there are also details you missed in the "instructions" - ie, the Datasheet, user manuals, etc - for your chip & the simulator.
So your first step should be to go back and check carefully in the "instructions".
