#137015 - right,but Responding to: ???'s previous message |
Jan,
Maybe you are right,i had readed the datasheet and see the context about interrupt,and know things should go in this way,that is why i am so confused. but,when i add the code below before set EA=1,the program can run 18 houres without any error,and without the code ,an error will be occured in few houres(sometime less than 1 hour) and cause the MCU died, if((TF0==1)&&((TI==1)||(RI==1))) { TI=0; RI=0; } thank you for reply |
