Dear all
After going through the datasheet of atmega 329 i came across a sentence which states that "As inputs, Port E pins that are externally pulled low will source current if the pull-up resistors are activated". What is the meaning of that sentence. If it is acting as input it should sink the current right? How can it source the curretn? Please give me a quick reply.Its urgent.
