MP10 شرح Flag (Status) Register (CF, ZF, AF, SF, PF, OF) & Loop control 80x86

The flag register is a 16-bit register sometimes referred to as the status register. only some of the bits are used. The rest are either undefined or reserved by Intel.
Six flags are called conditional flags, meaning that they indicate some condition that resulted after an instruction was executed. These six are CF, PF, AF, ZF, SF, and OF.
Three flags are sometimes called control flags since they are used to control the operation of instructions before they are executed. These control flags are DF, IF, TF.
