Description
0 = The internal system arbiter will park on the last PCI master to
use the PCI bus.
1 = The internal system arbiter will park on itself.
0 = Enable byte swapping in big endian mode from DCS to PCI
path.
1 = Disable byte swapping in big endian mode from DCS to PCI
path.
0 = Enable byte swapping in big endian mode from PCI to PCI mmio
registers.
1 = Disable byte swapping in big endian mode from PCI to PCI
mmio registers.
0 = Enable byte swapping in big endian mode from PCI to DCS.
1 = Disable byte swapping in big endian mode from PCI to DCS.
Enable write posting to internal PCI registers.
Enable write posting to XIO address range.
Enable write posting to pci_base2 address range.
Enable write posting to pci_base1 address range.
Enable monitoring of the SERR pin.
Read ahead to optimize PCI read latency to base 10.
Read ahead to optimize PCI read latency to base 14.
Read ahead to optimize PCI read latency to base 18.
Disable subword access to/from Base10 aperture.
Disable subword access to/from Base14 aperture.
Disable subword access to/from Base18 aperture.
Enables timer for 16 tic rule enforcer. This bit does not affect access
to the XIO aperture.
For internal address decoding: low bar of first aperture for external
PCI access. 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 that the PCI_Base1_lo be initialized
before the PCI_Base1_hi to avoid a potentially large segment of
address space being temporarily allocated to PCI space.
