PCI Configuration Access
PCI Configuration accesses are accomplished via the CONADD and
CONDAT registers. These two registers are implemented by the Raven
ASIC. In the CHRP memory map example, the CONADD and CONDAT
registers are located at 0xFE000CF8 and 0xFE000CFC, respectively. With
the PREP memory map, the CONADD register and the CONDAT register
are located at 0x80000CF8 and 0x80000CFC, respectively.
PCI Memory Maps
The PCI memory map is controlled by the Raven ASIC. The Raven ASIC
has flexible programming Map Decoder registers to customize the system
to fit many different applications.
Default PCI Memory Map
After a reset, the Raven ASIC turns all the PCI slave map decoders off.
Software must program the appropriate map decoders for a specific
environment.
PCI CHRP Memory Map
The following table shows a PCI memory map of the MTX that is CHRP-
compatible from the point of view of the PCI Local Bus.
