| timer0 problem on 12F683 |

hi
I try use timer0 on PIC12F683 but when I use timer0 I cant use other interrupts..
For example, my code if I remove timer0 function my interrupt int_ra3 work fine, if I use code like this, program break on enable_interrupts(INT_RA3)...

}

Program stop work when I have bold... someone know a solution to enable interrupt INT_RA3?
Best regards |

| this problem can not be a bug in CCS? |

| I'm newbie but I think PIN_A3 not support edge detect interrupt. I think only PIN_RA2 is support this |

Hi
thanks for your opinion but it support edge detect interrupt, because all work fine if I dont have "enable_interrupts(INT_TIMER0);"
when I dont use "enable_interrupts(INT_TIMER0);" I can enable and disable disable_interrupts(INT_RA3);
I think with the problem stay on INT_TIMER0 but I don't know where... :s |
