When B013 is ON, the data of double-length registers D0100×D0101 and BW20×BW21 are
added, and the result is stored in D0201×D0200. The RSTC is a instruction to reset the carry flag
before starting the calculation.
If the data of D0100×D0101 is 12345678 and BW20×BW21 is 54322, the result 12400000 is
stored in D0201ЧD0200.
