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).

Processing details
• 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 multiplication result in the device specified by (d).
• When (d) is a bit device, lower-order bit is specified first.
