Hello everybody! I have a problem with ATmega168 (will later be an mega88) and PB6/PB7. I'm trying to use these as output pins, ie. drive low-current LEDs by connecting PB6/PB7 via resistor and LED to +5V. That worked very good when I used PD5; but I need the PWM now and wanted to use PB6/PB7. I'm using the internal RC oscillator; timer 2 is currently unused, and if I need it later I'll only use it with clkIO and not asynchrone. Maybe I'm reading the datasheet wrong - but I believe these two pins are GPIO in my circumstances. Thank you for your hints! Regards, Phil

Remark: When I said that it doesn't work, I meant that pulling them low gives the pin 3.8V - not the expected 0V (GND).
