MDMA Configuration Structure definition.

Field Documentation

◆ BufferTransferLength

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)

◆ DataAlignment

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

◆ DestBlockAddressOffset

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

◆ DestBurst

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

Note
: the burst may be FIXED/INCR based on DestinationInc value , the BURST must be programmed as to ensure that the burst size will be lower than than BufferTransferLength

◆ DestDataSize

uint32_t MDMA_InitTypeDef::DestDataSize

Specifies the destination data size. This parameter can be a value of MDMA Destination data size

◆ DestinationInc

uint32_t MDMA_InitTypeDef::DestinationInc

Specifies if the Destination increment mode . This parameter can be a value of MDMA Destination increment mode

◆ Endianness

uint32_t MDMA_InitTypeDef::Endianness

Specifies if the MDMA transactions preserve the Little endianness. This parameter can be a value of MDMA Endianness

◆ Priority

uint32_t MDMA_InitTypeDef::Priority

Specifies the software priority for the MDMAy channelx. This parameter can be a value of MDMA Priority level

◆ Request

uint32_t MDMA_InitTypeDef::Request

Specifies the MDMA request. This parameter can be a value of MDMA Request selection

◆ SourceBlockAddressOffset

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

◆ SourceBurst

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

Note
: the burst may be FIXED/INCR based on SourceInc value , the BURST must be programmed as to ensure that the burst size will be lower than than BufferTransferLength

◆ SourceDataSize

uint32_t MDMA_InitTypeDef::SourceDataSize

Specifies the source data size. This parameter can be a value of MDMA Source data size

◆ SourceInc

uint32_t MDMA_InitTypeDef::SourceInc

Specifies if the Source increment mode . This parameter can be a value of MDMA Source increment mode

◆ TransferTriggerMode

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
