i use microcontroller IC T89C5115. But the programs loaded dont seem to work with consistency (i.e. it works sometimes and sometimes it may not even show a start pulse). i'm not able to detect whether the problem is in loading the microcontroller with the code(i use FLIP for that purpose) or due to any static in the microcontroller. Does anyone have any idea about safety feautres while handling microcontrollers or has faced similar problems ? thank you.
