DMA Current Source Address Lower (0-1) Registers
This is a read-only register that contains the lower bits (31:0) of the current source address for
a DMA transfer. If the source is VMEbus space, then this field represents a VMEbus address.
If the source 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 fill, with the VMEbus as the transfer source, this
register represents the VMEbus address at which a read error occurred. If a PCI/X bus error
occurs during a FIFO fill, with the PCI/X bus as the transfer source, this register represents
the PCI/X address at which a read error occurred.
