NOTES:
1. This opcode is reserved, but it does not generate an unimplemented opcode interrupt.
2. 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.”
