10.2 USB bus states
Reset state — When the USB bus is in the reset state, the USB system is stopped.
Operational state — When the USB bus is in the active state, the USB system is
operating normally.
Suspend state — When the USB bus is in the suspend state, the USB system is
stopped.
Resume state — When the USB bus is in the resume state, the USB system is operating
normally.
Each Host Controller contains a set of on-chip operational registers that are mapped to
uncached memory of the system addressable space. This memory space must begin on a
DWORD (32-bit) boundary. The size of the allocated space is defined by the initial value in
the Base Address register 0. HCDs must interact with these registers to implement USB
functionality.
After the PCI enumeration driver finishes the PCI device configuration, the new base
address of these memory-mapped operational registers is defined in BAR0. The HCD can
access these registers by using the address of base address value + offset.
Table 42
contains a list of Host Controller registers.
