OHCI register
Each Host Controller contains a set of on-chip operational registers that are mapped to
un-cached 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 48
For the OHCI Host Controller, there are only operational registers for the USB operation.
For the enhanced Host Controller, there are two types of registers: one set of read-only
capability registers, and one set of read and write operational registers.
