Trait cortex_m::interrupt::InterruptNumber [−][src]
Expand description
Trait for enums of external interrupt numbers.
This trait should be implemented by a peripheral access crate (PAC) on its enum of available external interrupts for a specific device. Each variant must convert to a u16 of its interrupt number, which is its exception number - 16.
Safety
This trait must only be implemented on enums of device interrupts. Each enum variant must represent a distinct value (no duplicates are permitted), and must always return the same value (do not change at runtime).
These requirements ensure safe nesting of critical sections.
