reset_boot_mode Settings
By using the non-boot mode reset initialization mode the user can change the internal register addresses from base 1800_0000 to base
1900_0000, as required. The RC32332 reset-boot mode initialization setting values and mode descriptions are listed below.
pci_host_mode Settings
During reset initialization, the RC32332’s PCI interface can be set to the Satellite or Host mode settings. When set to the Host mode, the CPU must
configure the RC32332’s PCI configuration registers, including the read-only registers. If the RC32332’s PCI is in the PCI-boot mode Satellite mode,
read-only configuration registers are loaded by the serial EEPROM.

PCI-boot mode (pci_host_mode must be in satellite mode) RC32332 will reset
either from a cold reset or from a PCI reset. Boot code is provided via PCI.
