GPDMA channel x transfer register 3
| SAO | source address offset increment The source address, pointed by GPDMA_CxSAR, is incremented or decremented (depending on GPDMA_CxBR1.SDEC) by this offset SAO[12:0] for each programmed source burst. This offset is not including and is added to the programmed burst size when the completed burst is addressed in incremented mode i.e. if GPDMA_CxTR1.SINC=1. Note: A source address offset must be aligned with the programmed data width of a source burst (c.f. SAO[2:0] vs GPDMA_CxTR1.SDW_LOG2[1:0]). Else a user setting error is reported and none transfer is issued. |
| DAO | destination address offset increment The destination address, pointed by GPDMA_CxDAR, is incremented or decremented (depending on GPDMA_CxBR1.DDEC) by this offset DAO[12:0] for each programmed destination burst. This offset is not including and is added to the programmed burst size when the completed burst is addressed in incremented mode i.e. if GPDMA_CxTR1.DINC=1. Note: A destination address offset must be aligned with the programmed data width of a destination burst (c.f. DAO[2:0] vs GPDMA_CxTR1.DDW_LOG2[1:0]). Else a user setting error is reported and none transfer is issued. Note: When the source block size is not a multiple of the destination burst size and is a multiple of the source data width, then the last programmed source burst is not completed and is internally shorten to match the block size. In this case, the additional GPDMA_CxTR3.SAO[12:0] is not applied. |
