Functions D*
(1) Performs the multiplication of BIN data specified at (S1) and the BIN data
speci-fied at (S2), and stores the multiplication result into the device specified at
(D).
(2) When (D) is a bit device, up to the lower 32 bits can be specified and the upper
32 bits cannot be specified.
Example
K1: Lower 4 bits (b0 to 3)
K4: Lower 16 bits (b0 to 15)
K8: 32 bits (b0 to 31)
When the upper 32-bit data of multiplication result is required for the bit device,
store the data to the word device and then transfer the data ((D)+2) and ((D)+3)
of word device to the specified bit device.
