Detailed Description
RAII class to block a peripheral interrupt.
The NVIC configuration for the specified IRQ is recorded and the interrupt disabled when the instance is constructed. When the instance is destructed the interrupt is enabled if it was enabled when constructed.
This allows safe manipulation of state that is shared between the application and the interrupt handler, assuming that instances of this class are created (for a specific IRQ) only when not invoked from within (recursively) the corresponding handler.
Note that if the code invoked from within the blocked region calls functions that independently block the same interrupt, the interrupt will not be prematurely re-enabled.
The documentation for this class was generated from the following file:
- nrfcxx/core.hpp
