Which of the following cases is true about the magnitude overflow bit in the status register? The overflow bit is set to 1 when subtracting when an overflow happens. The overflow bit is set to 1 when performing an addition and the sum results in a value larger than the A-out register. The overflow bit is set to 1 only when there is both a signed overflow and a regular overflow. The overflow bit is not set to 1 when subtracting when an overflow happens.
