PCI Registers
(continued)
Table 20. Base Address Register 0 (10h—13h)
The Base Address register is used to specify to the PCI operating system the memory size of the USS-344 device.
As recommended by the OpenHCI specification, the lower 12 bits are read only (fixed to logic 0) to indicate 4K
(2
12
) memory size.
Table 21. Base Address Register 1, 2, 3, 4, 5 (14h—17h), (18h—1Bh), (1Ch—1Fh), (20h—23h), (24h—27h)
These Base Address registers are unused by the USS-344 device.
Table 22. Cardbus CIS Pointer Register (28h—2Bh)
Cardbus CIS pointer not required for the USS-344.
Table 23. Subsystem Vendor ID Register (2Ch—2Dh)
The subsystem vendor ID is R/W for compliance with
Microsoft
PC98 specifications. On reset, this register is read
only. System BIOS may write a 1 to Special—Subsystem Write Capability register (4Ch) bit 0 to enable write capa-
bility of this register. After configuring this register, the system BIOS must write a 0 to Special—Subsystem Write
Capability register (4Ch) bit 0 to disable write capability of this register.
Table 24. Subsystem ID Register (2Eh—2Fh)
The subsystem vendor ID is R/W for compliance with
Microsoft
PC98 specifications. On reset, this register is read
only. System BIOS may write a 1 to Special—Subsystem Write Capability register (4Ch) bit 0 to enable write capa-
bility of this register. After configuring this register, the system BIOS must write a 0 to Special—Subsystem Write
Capability register (4Ch) bit 0 to disable write capability of this register.
Table 25. Expansion ROM Base Address Register (30h—33h)
Expansion ROM not supported by the USS-344.
