11.3 Registers
The Host Controller (HC) contains a set of on-chip operational registers that are used by the
Host Controller Driver (HCD). According to the function of these registers, they are divided
into four partitions, specifically for Control and Status, Memory Pointer, Frame Counter and
Root Hub. All of the registers should be read and written as Dwords. The memory map is
shown in
