Example
K1...........Lower 4 bits (b0 to b3)
K4...........Lower 16 bits (b0 to b15)
K8...........Lower 32 bits (b0 to b31)
If the upper 32 bits of the bit device are required for the result of the multiplication operation, first temporarily store the
data in a word device, then transfer the word device data to the bit device by designating ( +2) and ( +3) data.
