NOTE: All bit field instructions set the N and Z bits as shown for BFTST before performing the specified operation.
The MC68030 supports variable-length bit field operations on fields of up to
to the bit manipulation operations; bit field test (BFTST), bit field test and
32 bits. The bit field insert (BFINS) instruction inserts a value into a bit field.
