Purpose
Working
General
The Two’s Complement Overflow Flag V supports two’s complement arithmetics. See the
“Instruction Set Description” for detailed information.
The Negative Flag N indicates a negative result in an arithmetic or logic operation. See the
“Instruction Set Description” for detailed information.
The Zero Flag Z indicates a zero result in an arithmetic or logic operation. See the “Instruc-
tion Set Description” for detailed information.
The Carry Flag C indicates a carry in an arithmetic or logic operation. See the “Instruction
Set Description” for detailed information.
