Function Documentation

HAL_NOR_GetState()

HAL_NOR_StateTypeDef HAL_NOR_GetState

(

NOR_HandleTypeDef *

hnor

)

Return the NOR controller state.

Parameters

hnor	pointer to a NOR_HandleTypeDef structure that contains the configuration information for NOR module.

Return values

NOR	controller state

Definition at line 945 of file stm32l4xx_hal_nor.c.

{
  /* Return NOR handle state */
  return hnor->State;
}

HAL_NOR_GetStatus()

HAL_NOR_StatusTypeDef HAL_NOR_GetStatus	(	NOR_HandleTypeDef *	hnor,
		uint32_t	Address,
		uint32_t	Timeout
	)

Return the NOR operation status.

Parameters

hnor	pointer to a NOR_HandleTypeDef structure that contains the configuration information for NOR module.
Address	Device address
Timeout	NOR programming Timeout

Return values

NOR_Status

The returned value can be: HAL_NOR_STATUS_SUCCESS, HAL_NOR_STATUS_ERROR or HAL_NOR_STATUS_TIMEOUT
