BRSDEC=B_0x0, DDEC=B_0x0, SDEC=B_0x0, BRDDEC=B_0x0
GPDMA channel 12 alternate block register 1
| BNDT | block number of data bytes to transfer from the source |
| BRC | Block repeat counter |
| SDEC | source address decrement 0 (B_0x0): At the end of a programmed burst transfer from the source, the GPDMA_CxSAR register is updated by adding the programmed offset GPDMA_CxTR3.SAO to the current GPDMA_CxSAR value (current source address) 1 (B_0x1): At the end of a programmed burst transfer from the source, the GPDMA_CxSAR register is updated by subtracting the programmed offset GPDMA_CxTR3.SAO to the current GPDMA_CxSAR value (current source address) |
| DDEC | destination address decrement 0 (B_0x0): At the end of a programmed burst transfer to the destination, the GPDMA_CxDAR register is updated by adding the programmed offset GPDMA_CxTR3.DAO to the current GPDMA_CxDAR value (current destination address) 1 (B_0x1): At the end of a programmed burst transfer to the destination, the GPDMA_CxDAR register is updated by subtracting the programmed offset GPDMA_CxTR3.DAO to the current GPDMA_CxDAR value (current destination address) |
| BRSDEC | Block repeat source address decrement 0 (B_0x0): at the end of a block transfer, the GPDMA_CxSAR register is updated by adding the programmed offset GPDMA_CxBR2.BRSAO to the current GPDMA_CxSAR value (current source address) 1 (B_0x1): at the end of a block transfer, the GPDMA_CxSAR register is updated by subtracting the programmed offset GPDMA_CxBR2.BRSAO from the current GPDMA_CxSAR value (current source address) |
| BRDDEC | Block repeat destination address decrement 0 (B_0x0): at the end of a block transfer, the GPDMA_CxDAR register is updated by adding the programmed offset GPDMA_CxBR2.BRDAO to the current GPDMA_CxDAR value (current destination address) 1 (B_0x1): at the end of a block transfer, the GPDMA_CxDAR register is updated by subtracting the programmed offset GPDMA_CxBR2.BRDAO from the current GPDMA_CxDAR value (current destination address) |
