Operands:
S

: Multiplicand S
2
: Multiplicator D: Product
Explanations:
1. MUL16 and MUL16P are 16-bit instructions. MUL32 and MUL32P are 32-bit instructions.
2. The signed binary value in S
1
is multiplied by the signed binary value in S
2
, and the product is
stored in D. Notice that it is applicable to normal algebraic regulations.
3. If the sign bit is 0, it represents a positive value. If the sign bit is 1, it represents a negative value.
4. The models which are supported are DVP-ES2/EX2 v. 3.22, DVP-SS2 v. 3.20, DVP-SA2/SX2 v.
2.66, and DVP-SE v.1.60 (and above).
5. 16-bit binary multiplication
b15................ b0
X
=
b15................ b0
b15 is a sign bit. b15 is a sign bit.
b15 is a sign bit.

b15................ b0
16-bit value×16-bit value=16-bit value
If D is a bit device, users can use K1~K4, and form 16 bits. D only occupies 16 bits.

If D is a word device, users can use K1~K8, and forms 32 bits. D only occupies 32 bits.
