Explanation
1. This instruction multiplies the signed binary value in S
2. Only the MUL32 instruction can use an HC device.
3. 16-bit binary multiplication:
The product is a 16-bit value stored in D which is a 16-bit register. If b15 in D is 0, the product stored in D is a positive
value. If b15 in D is 1, the product stored in D is a negative value.
