Index
Type
Reset Value
This BAR sets the base address of the memory mapped USB controller registers. Bits [11:0] are read only (0000 0000
0000), indicating a 4 KB memory address range. Refer to Section 6.5.4 "Host Controller Native Registers" on page 294 for
the USB controller register bit formats and reset values.

BASE_ADDR
Description
Base Address. POST writes the value of the memory base address to this register.
Address Range (Always 0.) Indicates a 4k byte address range is requested.
Prefetch (Always 0). Indicates there is no support for prefetchable memory.
Width (Always 0). Indicates that the base register is 32-bits wide and can be placed
anywhere in 32-bit memory space.
Memory (Always 0). Indicates that the operational registers are mapped into memory
space.
Description
Interrupt Line. This register identifies which of the system interrupt controllers the
devices interrupt pin is connected to. The value of this register is used by device drivers
and has no direct meaning to the USB.
