Thank you for your reply Fiona,
Yes, there are the Advanced mode view, but I cant' find in that mode view an option to share the component Pin function. In my project I need to share the ADC input pin with a Analog Comparator input pin(not at same time). Yesterday, talking to a friend, I found a possible solution, that would be hand write the code for one component and use the Processor Expert for generenate the other, for example, add the ADC by Processor Expert and hand write the code for the Analog Comparator.
Perhaps this feature would be asked for the development team include in the future versions of the Processor Expert.
Thank you
