*5 You can only specify (.B) for the size specifier (.size).
*6 You cannot choose the same register for
src
and
dest
.
*7 If
src
is R0L, you can only choose A1 for
dest
as the address register.
*8 If
src
is R0H, you can only choose A0 for
dest
as the address register.
*9 You can specify (.B) and (.W) for the size specifier (.size).
