Host Controller Operational Registers
This section defines the enhanced host controller operational registers. These registers are located
after the capabilities registers. The operational register base must be DWord-aligned and is
calculated by adding the value in the first capabilities register (CAPLENGTH) to the base address
of the enhanced host controller register address space. All registers are 32 bits in length.
divided into two sets. The first set at offsets 00:3Fh are implemented in the core power well. Unless
otherwise noted, the core-well registers are reset by the assertion of any of the following:
