When in P (programme) exposure mode you dial in the ISO you want and the camera sets an appropriate value for Shutter speed and aperture. This option in the menu allows you to specify a "bias" to this selection, e.g. to favour a higher shutter speed (I think this is sports or action mode) or a wider aperture to give less DoF, or even (and this is one I use) the MTF setting, which chooses the aperture that gves the best resloution (provided the camera recognises the lens, which it should if a modern pentax one)
