Master Latency Timer Count (MLTC) — RO. Hardwired to 00h. Because the EHCI
controller is internally implemented with arbitration on an interface (and not PCI), it
does not need a master latency timer.
Base Address — R/W. Bits [31:10] correspond to memory address signals [31:10],
respectively. This gives 1-KB of locatable memory space aligned to 1-KB boundaries.
Reserved
Prefetchable — RO. Hardwired to 0 indicating that this range should not be prefetched.
Type — RO. Hardwired to 00b indicating that this range can be mapped anywhere
within 32-bit address space.
Resource Type Indicator (RTE) — RO. Hardwired to 0 indicating that the base address
field in this register maps to memory space.
Subsystem Vendor ID (SVID) — R/W (special). This register, in combination with the
USB 2.0 Subsystem ID register, enables the operating system to distinguish each
subsystem from the others.
NOTE: Writes to this register are enabled when the WRT_RDONLY bit (D29:F7,
D26:F7:80h, bit 0) is set to 1.
