**NOTE:** Here and afterwards, the word *"system"* refers to any code belonging to the operating system, hardware drivers or built-in apps.
To **ENABLE** a peripheral, call `furi_hal_bus_enable()`. At the time of the call, the peripheral in question **MUST** be disabled;
otherwise a crash will occur to indicate improper use. This means that any given peripheral cannot be enabled twice or more without disabling it first.
