Description

GPDMA channel x block register 2

Fields

BRSAO

Block repeated source address offset For a channel with 2D addressing capability, this field BRSAO[15:0] is used to update (by addition or subtraction depending on GPDMA_CxBR1.BRSDEC) the current source address (i.e. GPDMA_CxSAR) at the end of a block transfer. Note: A block repeated source address offset must be aligned with the programmed data width of a source burst (c.f. BRSAO[2:0] vs GPDMA_CxTR1.SDW_LOG2[1:0]). Else a user setting error is reported and none transfer is issued.

BRDAO

Block repeated destination address offset For a channel with 2D addressing capability, this field BRDAO[15:0] is used to update (by addition or subtraction depending on GPDMA_CxBR1.BRDDEC) the current destination address (i.e. GPDMA_CxDAR) at the end of a block transfer. Note: A block repeated destination address offset must be aligned with the programmed data width of a destination burst (c.f. BRDAO[2:0] vs GPDMA_CxTR1.DDW_LOG2[1:0]). Else a user setting error is reported and none transfer is issued.
