ISA Enable (ISAEN)
Needed to exclude legacy resource decode to route ISA resources
Needed to exclude legacy resource decode to route ISA resources
to legacy decode path. Modifies the response by the root port to
an I/O access issued by the processor that target ISA I/O
addresses. This applies only to I/O addresses that are enabled by
the IOBASE and IOLIMIT registers.
0 = All addresses defined by the IOBASE and IOLIMIT for
0 = All addresses defined by the IOBASE and IOLIMIT for
processor I/O transactions will be mapped to PCI Express-G.
1 = The root port will not forward to PCI Express-G any I/O
transactions addressing the last 768 bytes in each 1 KB
block, even if the addresses are within the range defined by
the IOBASE and IOLIMIT registers.
