Description

LPDMA channel 0 destination address register

Fields

DA

destination address This field is the pointer to the address from which the next data is written. During the channel activity, depending on the destination addressing mode (LPDMA_CxTR1.DINC), this field is kept fixed or incremented by the data width (LPDMA_CxTR1.DDW_LOG2[21:0]) after each single destination data, reflecting the next address from which data is written. In linked-list mode, after a LLI data transfer is completed, this register is automatically updated by DMA from the memory, provided the LLI is set with LPDMA_CxLLR.UDA = 1. Note: A destination address must be aligned with the programmed data width of a destination single (DA[2:0] versus LPDMA_CxTR1.DDW_LOG2[1:0]). Else, a user setting error is reported and no transfer is issued.
