53 / 508 page  Section 2 CPU Rev. 1.00 May 30, 2008 Page 33 of 484 REJ09B0436-0100 Table 2.3 Arithmetic Operations Instructions (2) 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. Note: * Refers to the operand size. B: Byte W: Word L: Longword |
