Table 14. Revision ID Register (08h)
Represents the current revision of the USS-344.
* The revision of the USS-344 can be identified either electronically or by physical markings. The revision can be identified
electronically using the standard PCI Revision ID register described in this table. The revision can also be identified by phys-
ical markings using the last letter of the USS-344 identifier code printed on the device. The USS-344 identifier code will be
printed using the format USS344XY, where X will identify the package type (M or T) and Y will identify the revision.
Table 15. Class Code Register (09h—0Bh)
The PCI class code for all OpenHCI host controllers is defined in the OpenHCI specification.
Table 16. Cache Line Size Register (0Ch)
No cache line is supported by the USS-344.
Table 17. Latency Timer Register (0Dh)
Controls the number of clock cycles the USS-344 may remain on the PCI bus after becoming bus master.
Table 18. Header Type Register (0Eh)
The USS-344 supports PCI header type 0 only.
Table 19. BIST Register (0Fh)
