It's just for configuration of the micro STM700

Hi

youssef.elmzaiti

,

Please refer to NVIC design hints and tips section in

http://www.st.com/content/ccc/resource/technical/document/programming_manual/group0/78/47/33/dd/30/37/4c/66/DM00237416/files/DM002374pdf/jcr:content/translations/en.DM002374pdf

:

The software uses the CPSIE I and CPSID I instructions to enable and disable interrupts. The CMSIS provides the following intrinsic functions for these instructions (STM32Cube_FW_F7_V1.7.0\Drivers\CMSIS\Include (@file core_cm7.h))

void __disable_irq(void) // Disable Interrupts

void __enable_irq(void) // Enable Interrupts

these two function is not available in core_cm7.h ! ( i don't use the HAL )

I believe they're in the compiler-specific headers, cmsis_armcc_V6.h or cmsis_gcc.h.
