<title>Description</title>
<para>
Each AVR microcontroller has pins which can be configured as digital
inputs. These are normally divided among some 'ports' (group of pins).
User has to select one of these port and which pin of that port as
digital input.
</para>
<para>
This is curretly dummy function. It provides no functionality but is required
for providing support for generating C code for AVR.
