Each register is connected with an internal bus of 16-bit wide, so the bit numbers of the
registers located at odd addresses are b15-b8, and those at even addresses are b7-b0.
Represents the initial state of each register immediately after reset with hexadecimal numbers.
The "H/W reset" is the reset by an external reset signal; the "S/W reset" is the reset by the
USBE bit of the USB Operation Enable Register.
