HAL_StatusTypeDef HAL_SPIEx_ConfigureUnderrun	(	SPI_HandleTypeDef *	hspi,
		uint32_t	UnderrunDetection,
		uint32_t	UnderrunBehaviour
	)

Configure the UNDERRUN condition and behavior of slave transmitter.

Parameters:

hspi,:	pointer to a SPI_HandleTypeDef structure that contains the configuration information for SPI module.
UnderrunDetection	: Detection of underrun condition at slave transmitter This parameter can be a value of SPI Underrun Detection.
UnderrunBehaviour	: Behavior of slave transmitter at underrun condition This parameter can be a value of SPI Underrun Behavior.

Return values:

None
