DMA Current Source Address Upper (0-1) Registers
This is a read-only register that contains the upper bits (63:32) 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 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.
