  * The @ref PAL has the advantage to make the access to the I/O ports platform
  * independent and still be optimized for the specific architectures.<br>
- * Currently the I/O ports interface does not handle physical port programming

- * and output operations but this may change in future releases.<br>
  * Note that the @ref PAL_LLD may also offer non standard macro and functions
