Subsystem ID (SID) — R/WO. BIOS sets the value in this register to identify the
Subsystem ID. The SID register, in combination with the SVID register (D29:F0/F1/F2/
F3:2C), enables the operating system to distinguish each subsystem from other(s). The
value read in this register is the same as what was written to the IDE_SID register.
NOTE: The software can write to this register only once per core well reset. Writes
Reserved
Base Address — R/W. Bits [15:5] correspond to I/O address signals AD [15:5],
respectively. This gives 32 bytes of relocatable I/O space.
Reserved
Resource Type Indicator (RTE) — RO. Hardwired to 1 to indicate that the base address
field in this register maps to I/O space.
Subsystem Vendor ID (SVID) — R/WO. BIOS sets the value in this register to identify
the Subsystem Vendor ID. The USB_SVID register, in combination with the USB
Subsystem ID register, enables the operating system to distinguish each subsystem
from the others.
NOTE: The software can write to this register only once per core well reset. Writes
should be done as a single, 16-bit cycle.
