359 / 590 page  Chapter 10 PCI Controller 10-97 10.5 PCI Configuration Space Register The PCI Configuration Space Register is accessed using PCI Configuration cycles by way of an external PCI host device only when in the Satellite mode. Table 10.5.1 lists registers contained within the PCI Configuration Space Register. The registers in the table with a shaded background are those whose values can be rewritten by software. (See 10.3.13.) Registers at addresses 0x00 through 0x41 can use the corresponding PCI Controller Control Register to access from the TX49/H2 core when in the Host mode. Please refer to the explanation of the corresponding PCI Controller Control registers for more information about these registers. This section only describes the registers that are accessed from the PCI Configuration Space. Also, it is possible to read some of the fields in the Status Register and PMCSR register from the Satellite Mode PCI Status Register. Please refer to the PCI Bus Specifications for more information on the PCI Configuration Register.
