Hi.
Suppose I am trying to burst from a host PC as a master, to a slave PCI
board, by copying data from the host memory, to the board, by the CPU.
What happens if my board stops the transaction by doing Retry, Disconnect
or Target-Abort, or the PCI arbitrator force the host to do a
Master-Abort?
How can the CPU know that the transaction was interrupted, and after how
many data phases?
Dose the host bridge generates some kind of exception the CPU in this
case?
I'd appreciate any comment.
Rafi Boneh.
