DMUL(P)(_U)
These instructions multiply the 32-bit binary data in the device specified by (s1) and the 32-bit binary data in the device
specified by (s2), and store the result in the device specified by (d).

■Descriptions, ranges, and data types
■Applicable devices
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 multiplication result in the device specified by (d).
• When nibble is specified ranging from K1 to K8 for (d), the result is obtained only for the lower-order 32 bits, and is not
obtained for the higher-order 32 bits. Transfer the data to word devices once, then execute the operation.
