Description

LPDMA channel 3 source address register

Fields

SA

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 (LPDMA_CxTR1.SINC), this field is either kept fixed or incremented by the data width (LPDMA_CxTR1.SDW_LOG2[1:0]) after each single source data, reflecting the next address from which data is read. In linked-list mode, after a LLI data transfer is completed, this register is automatically updated by LPDMA from the memory, provided the LLI is set with LPDMA_CxLLR.USA = 1. Note: A source address must be aligned with the programmed data width of a source single (SA[32:0] versus LPDMA_CxTR1.SDW_LOG2[1:0]). Else, a user setting error is reported and no transfer is issued.
