The process of converting the Input from an analog value to a digital value occurs for both analog inputs whenever the Configuration Register enables the inputs for analog processing. If nothing is connected to AN2 it is electrically floating, picking up stray electrical potential from the surroundings. Connecting it to GND will stop the random values.
