Reading this register returns the current contents of the port output register, not the physical port value. Writing to this register places corresponding intrefacing in all bits of the particular PORT pins.

As mentioned earlier every pin has a max of four functions. Please enable JavaScript to view the comments powered by Disqus.

Port Output Clear 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. This register controls the state of output pins.
