hardware events, RTFM also supports *software* tasks which can be spawned by the

Software tasks can also be assigned priorities and, under the hood, are

dispatched from interrupt handlers. RTIC requires that free interrupts are
declared in an `extern` block when using software tasks; some of these free
interrupts will be used to dispatch the software tasks. An advantage of software

Similarly, [`Sync`] is a marker trait for "types for which it is safe to share
references between threads", according to its definition in `core`. In the
context of RTFM the `Sync` trait is only required where it's possible for two,
context of RTIC the `Sync` trait is only required where it's possible for two,
or more, tasks that run at different priorities and may get a shared reference
(`&-`) to a resource. This only occurs with shared access (`&-`) resources.

Программным задачам также можно назначать приоритет и диспетчеризовать из

обработчиков прерываний. RTIC требует определения свободных прерываний в блоке
`extern`, когда используются программные задачи; эти свободные прерывания будут использованы, чтобы диспетчеризовать программные задачи. Преимущество программных
задач перед аппаратными в том, что на один обработчик прерывания можно назначить
множество задач.
