You mean atomic{} blocks, right?
In terms of language semantics, the promise is that code within an
atomic block will run atomically. In terms of implementations on
simple microcontrollers, this often means disabling all interrupts.
With interrupt priority levels one could, however, use some
intelligent compiler tricks to determine what IPL to disable. E.g.,
if the variables in the atomic section are only accessed by interrupt
priorities 1 and 3, you could set the IPL at 3.
