Parameters
<strong>FLAG</strong>specifies the FLASH flags to clear. This parameter can be any combination of the following values:
  • FLASH_FLAG_EOP : FLASH End of Operation flag
  • FLASH_FLAG_OPERR : FLASH operation Error flag
  • FLASH_FLAG_WRPERR: FLASH Write protected error flag
  • FLASH_FLAG_PGAERR: FLASH Programming Alignment error flag
  • FLASH_FLAG_PGPERR: FLASH Programming Parallelism error flag
  • FLASH_FLAG_PGSERR: FLASH Programming Sequence error flag
  • FLASH_FLAG_RDERR : FLASH Read Protection error flag (PCROP)
Return values
none

◆ __HAL_FLASH_DATA_CACHE_DISABLE

#define __HAL_FLASH_DATA_CACHE_DISABLE ( )    (FLASH->ACR &= (~FLASH_ACR_DCEN))

Disable the FLASH data cache.

Return values
none

◆ __HAL_FLASH_DATA_CACHE_ENABLE

#define __HAL_FLASH_DATA_CACHE_ENABLE ( )    (FLASH->ACR |= FLASH_ACR_DCEN)

Enable the FLASH data cache.

Return values
none

◆ __HAL_FLASH_DATA_CACHE_RESET

#define __HAL_FLASH_DATA_CACHE_RESET ( )
Value:
do {FLASH->ACR |= FLASH_ACR_DCRST; \

}while(0)

Resets the FLASH data Cache.

Note
This function must be used only when the data Cache is disabled.
Return values
None

none

◆ __HAL_FLASH_ENABLE_IT

#define __HAL_FLASH_ENABLE_IT (   __INTERRUPT__)    (FLASH->CR |= (__INTERRUPT__))

Enable the specified FLASH interrupt.

Parameters
<strong>INTERRUPT</strong>: FLASH interrupt This parameter can be any combination of the following values:
  • FLASH_IT_EOP: End of FLASH Operation Interrupt
