Function DB*
(1) Performs multiplication of the BCD data specified at (S1) and the BCD data
specified at (S2), and stores the multiplication result into the device specified at
(D).
(2) If (D) is a bit device, the 8 lower digits (32 lower bits) of the multiplication result
may only be specified.
K1 1 lower digit (B0 to 3), K4 4 lower digits (B0 to 15), K8 8 lower digits (B0 to
31)
(3) At (S1) and (S2), 0 to 99999999 (BCD 8 digits) can be specified.
