Detailed Description

Macro Definition Documentation

◆ cpu_irq_disable

#define cpu_irq_disable ( )
Value:
do { \
__disable_irq(); \
__DMB(); \
/*g_interrupt_enabled = false; */ \
} while (0)

◆ cpu_irq_enable

#define cpu_irq_enable ( )
Value:
do { \
/*g_interrupt_enabled = true; */ \
__DMB(); \
__enable_irq(); \
} while (0)

◆ irq_initialize_vectors

#define irq_initialize_vectors ( )
Value:
do { \
} while (0)

Initialize interrupt vectors.

For NVIC the interrupt vectors are put in vector table. So nothing to do to initialize them, except defined the vector function with right name.

This must be called prior to irq_register_handler.

◆ irq_register_handler

#define irq_register_handler (   int_num,
  int_prio 
)
Value:
NVIC_ClearPendingIRQ((IRQn_Type)int_num); \
NVIC_SetPriority((IRQn_Type)int_num, int_prio); \
NVIC_EnableIRQ((IRQn_Type)int_num); \
IRQn_Type

Definition: stm32h723xx.h:49

Register handler for interrupt.

For NVIC the interrupt vectors are put in vector table. So nothing to do to register them, except defined the vector function with right name.

Usage:

irq_register_handler(foo_irq_handler);
#define irq_initialize_vectors()
Initialize interrupt vectors.
Definition: compiler.h:321
#define irq_register_handler(int_num, int_prio)
Register handler for interrupt.
Definition: compiler.h:342
Note
The function func must be defined with the ISR macro.
The functions prototypes can be found in the device exception header files (exceptions.h).
