Don't write one in this bit (Initial value: 0, R/W).
Force Target Retry/Disconnect (Initial value: 0, R/W)
The PCI Controller executes Retry Termination on a PCI Read access transaction if
this bit is set to "1". This is a diagnostic function.
Force Target Abort (Initial value: 0, R/W)
The PCI Controller executes a Target Abort on a PCI Read access transaction if this
bit is set to "1". This is a diagnostic function.
Target read FIFO Reset (Initial value: 0, R/W)
The PCI Controller flushes the CORE internal Target Out-Bound FIFO when "1" is
written to this bit. This bit always reads out "0" when it is read. This is a diagnostic
function.
Target write FIFO Reset (Initial value: 0, R/W)
The PCI Controller flushes the CORE internal Target In-Bound FIFO when "1" is
written to this bit. This bit always read out "0" when it is read. This is a diagnostic
function.
