Hi, hope someone can save me some time here once again.
I am running an Atmega88 using internal 8MHz no divide by 8. I want to utilize PORTB , Pin 7 to turn high or low to enable/disable another IC.
Datasheet says that this is the external oscillator pin but can still be used as an IO pin if it is not configured to run an oscillator. I set DDRB to all 1s and then I set Port B to all 1s, every pin turns on except from pins 6 and 7.
What am I forgetting to do? Do I have to explicitly tell the thing that it is NOT running a crystal? How do I do this? I must have missed it in the datasheet but idk...
