struct HAL_DMA_MuxSyncConfigTypeDef

HAL DMA Synchro definition.

HAL DMAMUX Synchronization configuration structure definition

Definition at line 54 of file stm32l4xx_hal_dma_ex.h.

Data Fields
FunctionalState	EventEnable	Specifies if an event shall be generated once the RequestNumber is reached. This parameter can take the value ENABLE or DISABLE
uint32_t	RequestNumber	Specifies the number of DMA request that will be authorized after a sync event This parameter must be a number between Min_Data = 1 and Max_Data = 32
FunctionalState	SyncEnable	Specifies if the synchronization shall be enabled or disabled This parameter can take the value ENABLE or DISABLE
uint32_t	SyncPolarity	Specifies the polarity of the signal on which the DMA request is synchronized. This parameter can be a value of DMAMUX SyncPolarity selection
uint32_t	SyncSignalID	Specifies the synchronization signal gating the DMA request in periodic mode. This parameter can be a value of DMAMUX SyncSignalID selection
