The Root Hub registers are developed to maintain the similarity of bit organization
and operation to typical hubs found in the system.
Four registers are dened as follows:
HcRhDescriptorA
HcRhDescriptorB
HcRhStatus
HcRhPortStatus[1:NDP]
Each register is read and written as a Dword. These registers are only written during
initialization to correspond with the system implementation. The HcRhDescriptorA
and HcRhDescriptorB registers should be implemented such that they are writeable
regardless of the HCs USB states. HcRhStatus and HcRhPortStatus must be
writeable during the USBOPERATIONAL state.
10.3.1
HcRhDescriptorA register (12H—Read, 92H—Write)
The HcRhDescriptorA register is the rst register of two describing the characteristics
of the Root Hub. Reset values are implementation-specic (IS). The descriptor length
(11), descriptor type and hub controller current (0) elds of the hub Class Descriptor
are emulated by the HCD. All other elds are located in the registers
HcRhDescriptorA and HcRhDescriptorB.
Remark: IS denotes an implementation-specic reset value for that eld.
