Host Control (HC) Operational Registers
12.4.2 Control and Status Partition—MBAR + 0x1000
This HC partition uses 6 32-bit registers. These registers are located at an offset from MBAR of 0x1000. Register addresses are relative to
this offset. Therefore, the actual register address is: MBAR + 0x1000 + register address
The following registers are available:
USB HC Revision Register (0x1000)
USB HC Control Register (0x1004)
USB HC Command Status Register (0x1008)
USB HC Interrupt Status Register (0x100C)
USB HC Interrupt Enable Register (0x1010)
USB HC Interrupt Disable Register (0x1014)

12.4.2.1 USB HC Revision Register—MBAR + 0x1000

12.4.2.2 USB HC Control Register—MBAR + 0x1004

The HC Control register defines HC operating modes. Except for HostController FunctionalState and RemoteWakeUpConnected, most
fields in this register are modified only by the HCD.

24:31 REV Revision—a read-only field containing the BCD representation of the HCI specification
version implemented by this HC. For example, a value of 11h corresponds to version 1.1. All
HC implementations compliant with this specification have a value of 10h.
