I am trying to access PORT A pins, for some reason when i use the following pins, my connection to the network fails.
[url]DDRA |=(1 <<1);//high--postive polarity
DDRA |=(1 <<2);//high--negativ polarity
DDRA |=(1 <<3);//high--enable DC-DC[/url]
Once i comment this out it connects.
PORT A the ADC, but i want to use it as a normal GPIO.
Is there a limitation on which GPIO is can use and can not.
