DIV/DIVB/MUL/MULB (Note 2)

For the 8XC196KS and KT only, this opcode is reserved, but it does not generate an unimple-

mented opcode interrupt.

Signed multiplication and division are two-byte instructions. For each signed instruction, the

first byte is "FE" and the second is the opcode of the corresponding unsigned instruction. For

example, the opcode for MULU (3 operands) direct is "4C," so the opcode for MUL (3 oper-

ands) direct is "FE 4C."

Table A-8 lists instructions along with their lengths and opcodes for each applicable addressing

mode. A dash (—) in any column indicates "not applicable."
