///Field `SA` reader - source address This field is the pointer to the address from which the next data is read. During the channel activity, depending on the source addressing mode (HPDMA_CxTR1.SINC), this field is kept fixed or incremented by the data width (HPDMA_CxTR1.SDW_LOG2\[1:0\]) after each burst source data, reflecting the next address from which data is read. During the channel activity, this address is updated after each completed source burst, consequently to: the programmed source burst; either in fixed addressing mode or in contiguous-data incremented mode. If contiguously incremented (HPDMA_CxTR1.SINC = 1), then the additional address offset value is the programmed burst size, as defined by HPDMA_CxTR1.SBL_1\[5:0\] and HPDMA_CxTR1.SDW_LOG2\[21:0\] the additional source incremented/decremented offset value as programmed by HPDMA_CxBR1.SDEC and HPDMA_CxTR3.SAO\[12:0\] once/if completed source block transfer, for a channel x with 2D addressing capability (x = 12 to 15). additional block repeat source incremented/decremented offset value as programmed by HPDMA_CxBR1.BRSDEC and HPDMA_CxBR2.BRSAO\[15:0\] In linked-list mode, after a LLI data transfer is completed, this register is automatically updated by HPDMA from the memory, provided the LLI is set with HPDMA_CxLLR.USA = 1. Note: A source address must be aligned with the programmed data width of a source burst (SA\[2:0\] versus HPDMA_CxTR1.SDW_LOG2\[1:0\]). Else, a user setting error is reported and no transfer is issued. Note: When the source block size is not a multiple of the source burst size and is a multiple of the source data width, the last programmed source burst is not completed and is internally shorten to match the block size. In this case, the additional HPDMA_CxTR3.SAO\[12:0\] is not applied.
