Bytes/Cycles
*1 Marked by - - - cannot be selected.
*2 If dest is Rn or An while the size specifier (.size) is (.W), the number of bytes and cycles above are
increased by 1 each.
*3 If dest is neither Rn nor An while the size specifier (.size) is (.W), the number of bytes and cycles
above are increased by 1 and 2, respectively.
