STR720 - DMA CONTROLLER (DMAC)

86/401

9.4 Register description

The DMA registers are accessed via the APB bus and the register data path is 16 bit wide.

Source base address low X (DMASourceLoX) (X=2,3)

Address Offset: 80h - C0h

Reset value: 0000h

DMASourceLoX contains the low base address for stream X source DMA buffer.

Bit 15:0 = DMASourceLoX[15:0]

Source base address high X (DMASourceHiX) (X=2,3)

Address Offset: 84h - C4h

Reset value: 0000h

DMASourceHiX contains the high base address for stream X source DMA transfer.

Bit 15:0 = DMASourceHiX[15:0]

Destination base address low X (DMADestLoX) (X=2,3)

Address Offset: 88h - C8h

Reset value: 0000h

DMADestLoX contains the low base address for stream X destination DMA buffer.

Bit 15:0 = DMADestLoX[15:0]
