As mentioned earlier every pin has a max of four functions. Port Output Set Register. The current state of digital port pins can be read from this register, regardless of pin direction or alternate function selection as long as pins are not configured as an input to ADC.

Writing to this register places corresponding values in all bits of the particular PORT pins. Writing 1s produces lows at the corresponding port pins.
