Type Description
RO PCI error. Stores the address sent out on
the PCI bus ad<1:0> as a result of an I/O
transaction. The field logs the address of the
errors indicated by the NDEV, TABT, IOPE,
DDPE, IPTL, and IORT bits in the DCSR.
The register is valid only when one of these
error bits is set. If one of the bits is set, a
subsequent error of the same type will not
update the address logged in this register and
the LOST bit is set in DCSR.
