Functions *
(1) Performs the multiplication of BIN data specified at (S1) and the BIN data
specified at (S2), and stores the multiplication result into the device specified at
(D).
(2) When (D) is a bit device, specify the bits, beginning with the lower bits.
Example
K1: Lower 4 bits (b0 to 3)
K4: Lower 16 bits (b0 to 15)
K8: 32 bits (b0 to 31)
(3) At (S1) and (S2), -32768 to 32767 (BIN 16 bits) can be specified.
(4) The judgment of whether the data of (S1) and (S2) are positive or negative is
made at the highest bit (b15) and that of (D), at (b31).
