The reserved bits should always be written with the reset value.
11.1.7 HcHCCA register
The HcHCCA register contains the physical address of Host Controller Communication
Area (HCCA). The bit allocation is given in Table 55. The HCD determines alignment
restrictions by writing all 1s to HcHCCA and reading the content of HcHCCA. The
alignment is evaluated by examining the number of zeroes in lower order bits. The
