Port Output Set Register. Have an opinion, suggestionquestion or feedback about the article let it out here! Writing 1s produces highs at the corresponding port pins. The below sample code shows how to use the GPIO functions. It is recommended to configure the PORT direction and pin function before using ler. Retrieved from ” https: This register individually controls the direction of each port pin.

It is recommended to configure the PORT direction and pin function before using it. Please enable JavaScript to view the comments powered by Disqus.

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.

As mentioned earlier every pin has a max of interfaccing functions.

Reading this register returns the current contents of the port output register, not the physical port value. 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 ler an input to ADC.

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

As there can be up to 4 functions associated with a GPIO pin, two bits for each pin are available to select the function. As there can be up to 4 functions associated with a GPIO pin, two bits for each pin are available to select the function. Download the complete project folder from this link.
