Description
For internal address decoding: high bar of second aperture for
external PCI access (up to but not including). This register affects
the decode and routing of the bus controllers. It should not be relied
on as stable for 10 clocks after writing. It is recommended the
PCI_Base2_lo be initialized before the PCI_Base2_hi to avoid a
potentially large segment of address space being temporarily
allocated to PCI space. The PCI_Base2 aperture may be declared
as a internal view of PCI IO space or as PCI memory space. See
pci_io register for more information.
This register is the amount of time (in PCI clocks) the PCI will hold a
piece of data exclusively for an external PCI master. The timer is
initiated when the PCI can not complete the requested read in 16
clock cycles and issues a retry.
This register will be written with the address for the single data
phase cycle to be issued on the PCI bus. It will accept only 32-bit
writes. When issuing type 0 configuration transactions, the device
number (bits [15:11]) is expanded to bits [31:11] on the PCI bus as
defined in the PCI 2.2 spec.
This register will be written with the data for the single data phase
cycle to be issued on the PCI bus. This register will accept any size
write.
This register will hold data from the selected target after completion
of the read.
1 = cycle has completed. This bit can also be viewed in the
gppm_status register. Write to register 0x40FC8 to clear.
1 = initiate a PCI single data phase transaction on the PCI bus with
address “gppm_addr” and data “gppm_data.”
Command to be used with PCI cycle. Acceptable commands to use
in the command field include IO read, IO write, memory Read,
memory Write, configuration read and interrupt acknowledge. If
configuration management is enabled, configuration write may be
used.
