there are some pins on the ports of my port that are already set to 'high' initially, which means that even before I burn my program into the chip the LEDs already light up. After i burnt the program into the chip, the toggle switch don't seem to be able to control the few particular LEDs, no matter whether the toggle switch is on or off, the LEDs still light up. is there any way that i can actually set the few pins low initially before I burn my program into the chip? I hope i am clear enough, please tell me if you still find me not clear enough.

thanks
