The HC contains a set of on-chip control registers. These registers can be read or
written by the Host Controller Driver (HCD). The Control and Status register sets,
Frame Counter register sets, and Root Hub register sets are grouped under the
category of HC Operational registers (32 bits). These operational registers are made
compatible to OpenHCI (Host Controller Interface) Operational registers. This allows
the OpenHCI HCD to be easily ported to the ISP1161A1.
Reserved bits may be defined in future releases of this specification. To ensure
interoperability, the HCD must not assume that a reserved field contains logic 0.
Furthermore, the HCD must always preserve the values of the reserved field. When a
R/W register is modified, the HCD must first read the register, modify the bits desired,
and then write the register with the reserved bits still containing the original value.
Alternatively, the HCD can maintain an in-memory copy of previously written values
that can be modified and then written to the HC register. When a ‘write to set’ or ‘clear
the register’ is performed, bits written to reserved fields must be logic 0.
As shown in
32-bit Operational registers are similar to the offsets defined in the OHCI specification
with the addresses being equal to offset divided by 4.
