ST-LINK/V2 Pin Header

I want to use the ST-LINK/V2 to program a custom STM32F0 micro troght SWD.
Taking a look at ST-LINK/V2 User Manual (UM1075), I had a doubt about VAPP pins.
These pins (1 and 2), are input or output pins?
I guess these pins are inputs and should be connected to my power supply board, enabling the STLink to do identify the power supply level. Am I right?
