Setting this bit initiates the DMA operation. This bit will automatically clear when the
DMA is completed.
This bit, set to ’1’, indicates that a DMA with a length of zero was attempted.
This bit, set to ’1’, indicates that the on-chip address plus the DMA length yields a
value that exceeds the address pace of the on-chip memory.
This bit, set to ’1’, indicates that the on-chip virtual address provided to PPOCM in
combination with the DMA length results in a virtual page cross.
This bit, set to ’1’, indicates that the off-chip virtual address provided to PPOCM in
combination with the DMA length results in a virtual page cross.
This bit, set to ’1’, indicates that a virtual address mode DMA was started and the value
in the DMA length register is greater than 4K.
This bit, set to a '1,' indicates that a real address mode DMA was started and the value
in the DMA length register is greater than 64K.
This bit, set to a '1,' indicates that the off-chip memory and on-chip address written to
the DMA address registers must be either both real or both virtual.
