Macro Definition Documentation

#define CRITICAL_REGION_ENTER ( )
Value:
{ \
uint8_t IS_NESTED_CRITICAL_REGION = 0; \
uint32_t CURRENT_INT_PRI = current_int_priority_get(); \
if (CURRENT_INT_PRI != APP_IRQ_PRIORITY_HIGH) \
{ \
uint32_t ERR_CODE = sd_nvic_critical_region_enter(&IS_NESTED_CRITICAL_REGION); \
{ \
__disable_irq(); \
} \
else \
{ \
APP_ERROR_CHECK(ERR_CODE); \
} \
}

Macro for entering a critical region.

Note
Due to implementation details, there must exist one and only one call to CRITICAL_REGION_EXIT() for each call to CRITICAL_REGION_ENTER(), and they must be located in the same scope.
#define CRITICAL_REGION_EXIT ( )
Value:
if (CURRENT_INT_PRI != APP_IRQ_PRIORITY_HIGH) \
{ \
uint32_t ERR_CODE; \
__enable_irq(); \
ERR_CODE = sd_nvic_critical_region_exit(IS_NESTED_CRITICAL_REGION); \
{ \
APP_ERROR_CHECK(ERR_CODE); \
} \
} \
}

Macro for leaving a critical region.

Note
Due to implementation details, there must exist one and only one call to CRITICAL_REGION_EXIT() for each call to CRITICAL_REGION_ENTER(), and they must be located in the same scope.
#define NRF_APP_PRIORITY_THREAD   4

"Interrupt level" when running in Thread Mode.
