Description:
INSxL and INSxH shift bytes from register Ra and insert them into a field of zeros, storing the
result in register Rc. Register Rbv’<2:0> selects the shift amount, and the function code
selects the maximum field width: 1, 2, 4, or 8 bytes. The instructions can generate a byte,
word, longword, or quadword datum that is spread across two registers at an arbitrary byte
alignment.
