I'm trying to blink some leds using an ATmega163. I have one led on PORTB.0 that goes to GND through a 4k7 resistor. This one works fine. A second led on PORTA.0 going to GND doesn't blink. If I connect it to VCC, then is blinking. I checked the datasheet of ATmega163 and I didn't see any difference for ports A and B when they are configured as general I/O. What could be the explanation? Adrian
