effective address, then complements the field.
A field offset and a field width select the field. The field offset specifies the starting bit
of the field. The field width determines the number of bits in the field.
X — Not affected.
N — Set if the most significant bit of the field is set; cleared otherwise.
Z — Set if all bits of the field are zero; cleared otherwise.
V — Always cleared.
C — Always cleared.

For the MC68020, MC68030, and MC68040, all bit field
instructions access only those bytes in memory that contain
some portion of the bit field. The possible accesses are byte,
word, 3-byte, long word, and long word with byte (for a 5-byte
access).
