listed below.
16-bit binary addition:
1. If the operation result gotten is 0, a zero flag will be ON.
2. If the operation result gotten is less than –32,768, a borrow flag will
be ON.
3. If the operation result gotten is greater than 32,767, a carry flag will
be ON.
32-bit binary addition:
1. If the operation result gotten is 0, a zero flag will be ON.
2. If the operation result gotten is less than –2,147,483,648, a borrow
flag will be ON.
3. If the operation result gotten is greater than 2,147,483,647, a carry
flag will be ON.
