/*

При включенных уровнях оптимизации, компилятор может следить за тем,
|
||
присваиваем ли мы что-то переменной, и если нет — считать что это не переменная
|
||
а константа и выкинуть её из программы.
|
||
Ключевое слово volatile сообщает компилятору, что значение данного объекта
|
||
может быть изменено извне. Например (как это происходит в нашем случае),
|
||
значение может меняться контроллером периферийного устройства.
