It is often possible to choose peripheral input between internal signals and package pins. For example, figure below shows comparator input source selection offered in the AnalogComp_LDD component. There is list of pins and internal signals that can be used as comparator input. In Processor Expert, only pin names uses / (slash) separator (to distinguish individual pin functions). Internal signals do not contain this symbol in their name. This is how pins can be easily identified.
However, Processor Expert offers clear differentiation between internal signals and pins, as shown in figures below.
Clear differentiation is possible in property hint. In case of pins, full description of pin functions along with pin number on processor package is showed. If internal signal is selected then this fact is signalized at the last line of the hint.
