What exactly can be selected with the "Port drive strength select" bits?
What are the max. source/sink currents for the GPIOs and the total allowed current for the whole part?
Every GPIO can source/sink a maximum current of 2mA (single drive) and 4mA (full drive) .16 GPIOs allowed to switch at any given point in time with a max load of 4mA (full drive) , Which meas the whole part can sink/source a max of 64mA
