Master Mode Operation
The PCI MegaCore functions support both 64-bit and 32-bit transactions.
The pci_mt64 function supports the following 64-bit PCI memory
transactions:
■
64-bit burst memory read/write
■
64-bit single-cycle memory read/write

64-bit single-cycle memory write transactions are only
supported if the Assume ack64n Response option is turned on
in the Parameterize - PCI Compiler wizard. For more
