Adding
(I1 + I2 = QV)
2174 1 = QV contains the last per-
missible value as an overflow has occurred.
The carry bit AR..CY is set to 1.
SUB - Subtracter
Subtracting
(I1 - I2 = QV)
-2174483648 - 3 = QV contains the last per-
missible value as an overflow has occurred.
The carry bit AR..CY is set to 1.
MUL - Multiplier
Multiplying
(I1 * I2 = QV)
1000042 * 2401 = QV contains the last per-
missible value as an overflow has occurred.
The carry bit AR..CY is set to 1.
