Multiplying 16-bit binary data
*(P)(_U) instruction and MUL(P)(_U) instruction can be used for multiplication of 16-bit binary data.
*(P)(_U)
These instructions multiply the 16-bit binary data in the device specified by (s1) by the 16-bit binary data in the device
specified by (s2), and store the result in the device specified by (d).

• When (d) is a bit device, lower-order bit is specified first.
Ex.
Multiplication result when (d) is a bit device
• K1 ... Lower 4 bits (b0 to b3)
• K4 ... Lower 16 bits (b0 to b15)
• K8 ... Lower 32 bits (b0 to b31)
