10.3.1 HcRhDescriptorA register (R/W: 12H/92H)
Four 32-bit registers have been defined:
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 are writeable regardless of the
HC’s USB states. HcRhStatus and HcRhPortStatus are writeable during the
USBOperational state only.
The HcRhDescriptorA register is the first register of two describing the characteristics
of the Root Hub. Reset values are Implementation-Specific (IS). The descriptor length
(11), descriptor type and hub controller current (0) fields of the hub Class Descriptor
are emulated by the HCD. All other fields are located in registers HcRhDescriptorA
and HcRhDescriptorB.
Remark: IS denotes an implementation-specific reset value for that field.
Code (Hex): 12 — read
Code (Hex): 92 — write
