uint32_t _ll_dma_init::block_size |
Specifies the number of data to transfer, in data unit. The data unit is equal to the source buffer configuration set in src_data_width parameters. This parameter must be a value between Min_Data = 0 and Max_Data = 0xFFF
This feature can be modified afterwards using unitary function ll_dma_set_block_size().
uint32_t _ll_dma_init::direction |
Specifies if the data will be transferred from memory to peripheral, from memory to memory or from peripheral to memory or form peripheral to peripheral. This parameter can be a value of Transfer Direction
This feature can be modified afterwards using unitary function ll_dma_set_data_transfer_direction().
uint32_t _ll_dma_init::dst_address |
uint32_t _ll_dma_init::dst_data_width |
Specifies the Destination transfer width alignment(byte, half word, word). This parameter can be a value of Destination data alignment
This feature can be modified afterwards using unitary function ll_dma_set_destination_width().
uint32_t _ll_dma_init::dst_increment_mode |
Specifies whether the Destination address is incremented or decrement or not. This parameter can be a value of Destination increment mode
This feature can be modified afterwards using unitary function ll_dma_set_destination_increment_mode().
uint32_t _ll_dma_init::dst_peripheral |
Specifies the Destination peripheral type. This parameter can be a value of DMA Peripheral type
This feature can be modified afterwards using unitary function ll_dma_set_destination_peripheral().
uint32_t _ll_dma_init::priority |
Specifies the channel priority level. This parameter can be a value of Transfer Priority level
This feature can be modified afterwards using unitary function ll_dma_set_channel_priority_level().
uint32_t _ll_dma_init::src_address |
uint32_t _ll_dma_init::src_data_width |
Specifies the Souce transfer width alignment(byte, half word, word). This parameter can be a value of Source data alignment
This feature can be modified afterwards using unitary function ll_dma_set_source_width().
uint32_t _ll_dma_init::src_increment_mode |
Specifies whether the Source address is incremented or decrement or not. This parameter can be a value of Source increment mode
This feature can be modified afterwards using unitary function ll_dma_set_source_increment_mode().
uint32_t _ll_dma_init::src_peripheral |
Specifies the Source peripheral type. This parameter can be a value of DMA Peripheral type
This feature can be modified afterwards using unitary function ll_dma_set_source_peripheral().
