/*
*
* Header for high performance Arduino Digital I/O
*
* Automatically generated from the Arduino library setup (boards.txt & pins_arduino.h)
*
* See the accompanying file README.md for documentation.
*
* ****
*
* This header is a derived work of the Arduino microcontroller libraries, which are
* licensed under LGPL. Although as a header file it is not bound by the same usage
* clauses as the library itself (see "3. Object Code Incorporating Material from
* Library Header Files.)"
*
* Note that although the code generated functions below here look horrific,
* they're written to inline only very small subsets of themselves at compile
* time (they generate single port-register instructions when the parameters
* are constant.)
