Texas Instruments PCI7611 PC Card Applications, Function 2 Ohci 1394 Subsystem Identification

3.4.5Function 2 (OHCI 1394) Subsystem Identification

The subsystem identification register is used for system and option card identification purposes. This register can be initialized from the serial EEPROM or programmed via the subsystem access register at offset F8h in the PCI configuration space (see Section 7.25, Subsystem Access Register). See Table 7−22 for a complete description of the register contents.

Write access to the subsystem access register updates the subsystem identification registers identically to OHCI-Lynx.The contents of the subsystem access register are aliased to the subsystem vendor ID and subsystem ID registers at Function 2 PCI offsets 2Ch and 2Eh, respectively. The system ID value written to this register may also be read back from this register. See Table 7−22 for a complete description of the register contents.

3.4.6Function 3 (Flash Media) Subsystem Identification

The subsystem identification register is used for system and option card identification purposes. This register can be initialized from the serial EEPROM or programmed via the subsystem access register at offset 50h in the PCI configuration space (see Section 11.22, Subsystem Access Register). See Table 11−15 for a complete description of the register contents.

The contents of the subsystem access register are aliased to the subsystem vendor ID and subsystem ID registers at Function 3 PCI offsets 2Ch and 2Eh, respectively. See Table 11−15 for a complete description of the register contents.

3.4.7Function 4 (SD Host) Subsystem Identification

The subsystem identification register is used for system and option card identification purposes. This register can be initialized from the serial EEPROM or programmed via the subsystem access register at offset 8Ch in the PCI configuration space (see Section 12.23, Subsystem Access Register). See Table 12−16 for a complete description of the register contents.

The contents of the subsystem access register are aliased to the subsystem vendor ID and subsystem ID registers at Function 4 PCI offsets 2Ch and 2Eh, respectively. See Table 12−16 for a complete description of the register contents.

3.4.8Function 5 (Smart Card) Subsystem Identification

The subsystem identification register is used for system and option card identification purposes. This register can be initialized from the serial EEPROM or programmed via the subsystem access register at offset 50h in the PCI configuration space (see Section 13.23, Subsystem ID Alias Register). See Table 13−14 for a complete description of the register contents.

The contents of the subsystem access register are aliased to the subsystem vendor ID and subsystem ID registers at Function 5 PCI offsets 2Ch and 2Eh, respectively. See Table 13−14 for a complete description of the register contents.
