A mutex may lead to sleep and it's illegal to sleep in an interrupt service routine. Anyway, you can't use a mutex within an interrupt (because you can't put interrupt handlers to sleep), however you can use a spin lock instead. Spin locks are better because they are optimized for the... grilled bratwurst time
