MDMA Configuration Structure definition.
uint32_t MDMA_InitTypeDef::BufferTransferLength |
Specifies the buffer Transfer Length (number of bytes), this is the number of bytes to be transferred in a single transfer (1 byte to 128 bytes)
uint32_t MDMA_InitTypeDef::DataAlignment |
Specifies the source to destination Memory data packing/padding mode. This parameter can be a value of MDMA data alignment
int32_t MDMA_InitTypeDef::DestBlockAddressOffset |
this field specifies the Next block destination address offset signed value : if > 0 then increment the next block destination Address by offset from where the last block ends if < 0 then decrement the next block destination Address by offset from where the last block ends if == 0, the next block destination address starts from where the last block ends
uint32_t MDMA_InitTypeDef::DestBurst |
Specifies the Burst transfer configuration for the destination memory transfers. It specifies the amount of data to be transferred in a single non interruptible transaction. This parameter can be a value of MDMA Destination burst
uint32_t MDMA_InitTypeDef::DestDataSize |
Specifies the destination data size. This parameter can be a value of MDMA Destination data size
uint32_t MDMA_InitTypeDef::DestinationInc |
Specifies if the Destination increment mode . This parameter can be a value of MDMA Destination increment mode
uint32_t MDMA_InitTypeDef::Endianness |
Specifies if the MDMA transactions preserve the Little endianness. This parameter can be a value of MDMA Endianness
uint32_t MDMA_InitTypeDef::Priority |
Specifies the software priority for the MDMAy channelx. This parameter can be a value of MDMA Priority level
uint32_t MDMA_InitTypeDef::Request |
Specifies the MDMA request. This parameter can be a value of MDMA Request selection
int32_t MDMA_InitTypeDef::SourceBlockAddressOffset |
this field specifies the Next block source address offset signed value : if > 0 then increment the next block source Address by offset from where the last block ends if < 0 then decrement the next block source Address by offset from where the last block ends if == 0, the next block source address starts from where the last block ends
uint32_t MDMA_InitTypeDef::SourceBurst |
Specifies the Burst transfer configuration for the source memory transfers. It specifies the amount of data to be transferred in a single non interruptible transaction. This parameter can be a value of MDMA Source burst
uint32_t MDMA_InitTypeDef::SourceDataSize |
Specifies the source data size. This parameter can be a value of MDMA Source data size
uint32_t MDMA_InitTypeDef::SourceInc |
Specifies if the Source increment mode . This parameter can be a value of MDMA Source increment mode
uint32_t MDMA_InitTypeDef::TransferTriggerMode |
Specifies the Trigger Transfer mode : each request triggers a : a buffer transfer, a block transfer, a repeated block transfer or a linked list transfer This parameter can be a value of MDMA Transfer Trigger Mode
