Instruction Size* Function
DIVXS
B/W Rd ÷ Rs → Rd
Performs signed division on data in two general registers: either 16 bits
÷ 8 bits → 8-bit quotient and 8-bit remainder or 32 bits ÷ 16 bits → 16-bit
quotient and 16-bit remainder.
CMP
B/W/L
Rd – Rs, Rd – #IMM
Compares data in a general register with data in another general
register or with immediate data, and sets CCR bits according to the
result.
NEG
B/W/L
0 – Rd → Rd
Takes the two's complement (arithmetic complement) of data in a
general register.
EXTU
W/L
Rd (zero extension) → Rd
Extends the lower 8 bits of a 16-bit register to word size, or the lower 16
bits of a 32-bit register to longword size, by padding with zeros on the
left.
EXTS
W/L
Rd (sign extension) → Rd
Extends the lower 8 bits of a 16-bit register to word size, or the lower 16
bits of a 32-bit register to longword size, by extending the sign bit.

Function
Rd ∧ Rs → Rd, Rd ∧ #IMM → Rd
Performs a logical AND operation on a general register and another
general register or immediate data.
Rd ∨ Rs → Rd, Rd ∨ #IMM → Rd
Performs a logical OR operation on a general register and another
general register or immediate data.
Rd ⊕ Rs → Rd, Rd ⊕ #IMM → Rd
Performs a logical exclusive OR operation on a general register and
another general register or immediate data.
¬ (Rd) → (Rd)
Takes the one's complement of general register contents.
