In 8 bit signed number operations, OV flag is set to 1 if:
A. a carry is generated from D7 bit
B. a carry is generated from D3 bit
C. a carry is generated from D7 or D3 bit
D. a carry is generated from D7 or D6 bit
Answer:A
In 8 bit signed number operations, OV flag is set to 1 if:
A. a carry is generated from D7 bit B. a carry is generated from D3 bit C. a carry is generated from D7 or D3 bit D. a carry is generated from D7 or D6 bit
Explanation: In 8 bit operations, if a carry is generated from D6 or D7 bit, then OV flag is set to 1.
