FMC_NAND_ECC_Disable()

HAL_StatusTypeDef FMC_NAND_ECC_Disable	(	FMC_NAND_TypeDef *	Device,
		uint32_t	Bank
	)

Disables dynamically FMC_NAND ECC feature.

Parameters

Bank	NAND bank number

Return values

HAL

status

{
  /* Check the parameters */
  assert_param(IS_FMC_NAND_DEVICE(Device));

  /* Prevent unused argument(s) compilation warning if no assert_param check */
  UNUSED(Bank);

  /* Disable ECC feature */
  CLEAR_BIT(Device->PCR, FMC_PCR_ECCEN);

  return HAL_OK;
}

FMC_NAND_ECC_Enable()

HAL_StatusTypeDef FMC_NAND_ECC_Enable	(	FMC_NAND_TypeDef *	Device,

{
  /* Check the parameters */
  assert_param(IS_FMC_NAND_DEVICE(Device));

  /* Prevent unused argument(s) compilation warning if no assert_param check */
  UNUSED(Bank);

  /* Enable ECC feature */
  SET_BIT(Device->PCR, FMC_PCR_ECCEN);

  return HAL_OK;
}

FMC_NAND_GetECC()

HAL_StatusTypeDef FMC_NAND_GetECC	(	FMC_NAND_TypeDef *	Device,
		uint32_t *	ECCval,
		uint32_t	Bank,
		uint32_t	Timeout
