Host Controller
This block is the operational control block in the USB core. It is responsible for the host controller operational states (Suspend,
Disabled, Enabled), special USB signaling (Reset, Resume), status, interrupt control, and host controller configuration
information.
The host controller (HC) interface registers are PCI memory mapped I/O, hereafter referred to as MEMOFST. Table 4-2 gives
a register map for the MEMOFST register space. Refer to Section 5.2, "Host Controller Register Space" for detailed bit
information.
