must configure the RC32334’s PCI configuration registers, including the read-only registers. If the RC32334’s PCI is in the PCI-boot mode Satellite
mode, read-only configuration registers are loaded by the serial EEPROM.

By using the non-boot mode cold reset initialization mode the user can change the internal register addresses from base 1800_0000 to base
During cold reset initialization, the RC32334’s PCI interface can be set to the Satellite or Host mode settings. When set to the Host mode, the CPU

PCI-boot mode (pci_host_mode must be in satellite mode)
RC32334 will reset either from a cold reset or from a PCI
reset. Boot code is provided via PCI.
Standard-boot mode
Boot from the RC32334’s memory controller (typical system).
Boot-Prom Width specifies the memory port
width of the memory space which contains
the boot prom.
PCI is in satellite mode
PCI is in host mode (typical system)
