Processing details
• These instructions multiply the 32-bit binary data in the device specified by (s1) by the 32-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, only the lower 32 bits of the operation result are stored. If the upper 32 bits of the operation result
are required, temporarily store the result in a word device, and transfer the data stored in (d)+2 and (d)+3 to the specified
bit devices.
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.
