Communication Area. The Host Controller Driver determines the alignment restrictions by
writing all ones to HcHCCA and reading the content of HcHCCA. The alignment is
evaluated by examining the number of zeros in the lower order bits. The minimum
alignment is 256 bytes. Therefore, bits 0 through 7 always return 0 when read. This area is
used to hold the control structures and the Interrupt table that are accessed by both the
Host Controller and the Host Controller Driver.
The HcHCCA register contains the physical address of the Host Controller
