What is the Parity Flag (PF) used for?
Correct! Well done.
Incorrect.
The correct answer is B) Set when the low byte of the result has an even number of 1-bits; used historically for data transmission error detection
B
Correct Answer
Set when the low byte of the result has an even number of 1-bits; used historically for data transmission error detection
Explanation
PF=1 if the number of set bits in the low byte of the result is even. JPE/JPO use PF. Rarely used in modern code but available for SIMD status operations.
