The Arduino IDE and configure SPI pins I / o...

Good, Habr.
Trying to go from Arduino to AVR net was thrown first to the ATMega328P-PU to flash it via UNO sketch from the Arduino IDE. Let's just say have made the first step.
But there is one problem. According to the scheme I have ports MOSI, SS, SCK and OC1A are used as OUTPUT and MISO as INPUT. Judging by the datasheet, these pins can be used as an INT, but I don't know if they are so set in the Arduino IDE. The problem is that the debug Board is at home and check it out right now I can't. Himself at work with glossy paper and a laser printer. Here I sit and think: to print / not to print?

From what I found on the Internet, it's real. However, I would like to know the actual situation.

Please help me with this issue. Thanks in advance for answers
