/* To achieve GPIO toggling maximum frequency, the following sequence is mandatory.
You can monitor PD0 or PD2 on the scope to measure the output signal.
If you need to fine tune this frequency, you can add more GPIO set/reset
cycles to minimize more the infinite loop timing.
This code needs to be compiled with high speed optimization option. */
