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 operation result in the device specified by (d).

• When (d) is a bit device, data should be specified in order from lower bits.
Ex.
Operation 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)
Operation error
There is no operation error.
