"atomic" shuts off interrupts for the duration of the block.
Since only one task can run at a time, and it can only be
interrupted by hardware -- mostly the async functions --
this means that anything in an atomic block will run to
completion before any other code gets executed. I think
this is your option #2.

1. 2 atomic block will not preempt each other
2. when atomic block is executing, it cannot be preempted eg. by another
async block
Thank you in advance. :D
