Convenience macros for the management of interrupts globally within the device.
Macros and functions to create and control global interrupts within the device.

| void Name (void) __attribute__((__interrupt__)) __VA_ARGS__; void Name (void) |
Macro for the definition of interrupt service routines, so that the compiler can insert the required prologue and epilogue code to properly manage the interrupt routine without affecting the main thread's state with unintentional side-effects.
Interrupt handlers written using this macro may still need to be registered with the microcontroller's Interrupt Controller (if present) before they will properly handle incoming interrupt events.
- Note
- This macro is only supplied on some architectures, where the standard library does not include a valid definition. If an existing definition exists, the alternative definition here will be ignored.
- Parameters
-
Name | Unique name of the interrupt service routine. |
Definition at line 225 of file Common.h.
Retrieves a mask which contains the current state of the global interrupts for the device. This value can be stored before altering the global interrupt enable state, before restoring the flag(s) back to their previous values after a critical section using SetGlobalInterruptMask().
- Returns
- Mask containing the current Global Interrupt Enable Mask bit(s).

Disabled global interrupt handling for the device, preventing interrupts from being handled.

static void GlobalInterruptEnable |

|
|
inlinestatic |
Enables global interrupt handling for the device, allowing interrupts to be handled.

static void SetGlobalInterruptMask |

const uint_reg_t |
GlobalIntState | ) |
|
|
inlinestatic |
Sets the global interrupt enable state of the microcontroller to the mask passed into the function. This can be combined with GetGlobalInterruptMask() to save and restore the Global Interrupt Enable Mask bit(s) of the device after a critical section has completed.
- Parameters
-
GlobalIntState | Global Interrupt Enable Mask value to use |
