Chapter 10 PCI Controller

10-5

Registers in the PCI Controller Control Register that include an offset address in the range from

0xD000 to 0xD07F can only be accessed when in the Host mode and cannot be accessed when in the

Satellite mode. These registers correspond to PCI Configuration Space Registers that an external PCI

Host device accesses when in the Satellite mode. Section “10.4 PCI Controller Control Register”

explains each register in detail.

Figure 10.3.1 illustrates the register map when in the Host mode. Figure 10.3.2 illustrates the register

map when in the Satellite mode.
