Notes: 1. When n = 0, correct operation is not guaranteed.
2. When n is an odd number, insert a dummy word of 0 at the end.
3. The longword address following the LINK Address is handled as the next command
code. Therefore, do not specify the longword address following the address where the
LINK Address is to be assigned as the link destination address specified by the LINK
Address.
