The F31 output is the most.
The 8-bit adder/subtractor illustrated in Fig. 4.1.4 is designed to add or subtract 8−bit binary numbers using twos complement notation. In this system the most significant bit (bit 7) is not used as part of the number’s value, it is used to indicate the sign of the number (0 = positive and 1 = negative)..
