MC68340 USER’S MANUAL
MOTOROLA
5.3.3.3 INTEGER ARITHMETIC OPERATIONS. The arithmetic operations include the
four basic operations of add (ADD), subtract (SUB), multiply (MUL), and divide (DIV) as
well as arithmetic compare (CMP, CMPM, CMP2), clear (CLR), and negate (NEG). The
instruction set includes ADD, CMP, and SUB instructions for both address and data
operations with all operand sizes valid for data operations. Address operands consist of
16 or 32 bits. The clear and negate instructions apply to all sizes of data operands.
Signed and unsigned MUL and DIV instructions include:
• Word multiply to produce a long-word product
• Long-word multiply to produce a long-word or quad-word product
• Division of a long-word dividend by a word divisor (word quotient and word
remainder)
• Division of a long-word or quad-word dividend by a long-word divisor (long-word
quotient and long-word remainder)
A set of extended instructions provides multiprecision and mixed-size arithmetic. These
instructions are add extended (ADDX), subtract extended (SUBX), sign extend (EXT), and
negate binary with extend (NEGX). Refer to Table 5-5 for a summary of the integer
arithmetic operations.
