reset_boot_mode Settings
By using the non-boot mode cold reset initialization mode the user can change the internal register addresses from base 1800_0000 to base
1900_0000, as required. The RC32334 cold reset-boot mode initialization setting values and mode descriptions are listed below.

Reset Boot Mode
Description
pci_host_mode Settings
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
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.
