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 (MEM_BASE). Since CAPLENGTH is always 20h,
this offset. All registers are 32 bits in length.
Software must read and write these registers using only DWord accesses.These
registers are divided into two sets. The first set at offsets MEM_BASE + 00:3Bh are
E + Offset
