First i make you my apologise for my bad english.
Second please look on picture below before reading.
Now, i'm trying to build a test-bench (a program that run out Atmel Studio), for do this system i need to change the input status on line program like this:
PINB (0) = "1" --> where PINB is the port that is set in input mode and (0) is the bit0 of this port and "1" is the logical staus;
or like this : set PINB,0b00000001;
or through a scripting, (better for me is on line program if is possible).
