The default values are defined with an h for hex, a bi for binary, or 00 for zero. If there
is not a letter following the default value, assume it is a binary number.
Address locations that are not listed are considered reserved register locations. Reads
to reserved registers may return non-zero values. Writes to reserved locations may
cause system failure.
Reserved bits are Read Only.
