I/O Pin Structures
The accompanying diagram illustrates the internal structure of the I/O logic function. As the exact
logical construction of the I/O pin will differ from this drawing, it is supplied as a guide only to
assist with the functional understanding of the I/O logic function. The wide range of pin-shared
structures does not permit all types to be shown.
