6 BASIC INSTRUCTIONS
6.2 Arithmetic Operation Instructions
MUL(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).
*1 The MUL instruction is not supported by the ST language. Use MUL of the standard function.
