Once the local bus has been set up to interface to the PCI-DP, it does have access to all of the operations registers. However, it is not recommended to try to configure the PCI-DP from the local bus instead of an EEPROM. This is because the local bus processor has to come out of reset and ensure that the PCI-DP has come out of reset and then program it all before the PCI Bus Master starts its bus scan. This is a race condition that any developer should avoid. Also, the default LBUSCFG setting is only compatible to a few local processors. This interface must be set up and working before the local processor can access the Operations Registers.
