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. contents: zero flag overflow flag auxiliary carry flag carry flag status register flag register parity flag interrupt flag sign flag trap flag direction flag ADD ADC (add with carry) STC CLC CMC conditional and unconditional jump loop in assemply JMP JNZ JZ #voltuino #فولتوينو
