DMA Current Destination Address Lower (0-1) Registers
This is a read-only register that contains the lower bits (31:0) of the current destination
address for a DMA transfer. If the destination is VMEbus space, then this field represents a
VMEbus address. If the destination is PCI/X space, then this field represents a PCI/X address.
Software can read this register after a DMA error to determine how far along a DMA transfer
went before the error occurred.
If a VMEbus error occurs during a FIFO empty, with the VMEbus as the transfer destination,
this register represents the VMEbus address at which a write error occurred. If a PCI/X bus
error occurs during a FIFO empty, with the PCI/X bus as the transfer destination, this register
represents the PCI/X address at which a write error occurred.
