* zero Set if a result equals zero.
sample asm inst to test: jnz , jz

* carry flag (ada sisa)
sample asm ins to tes: jz (jump if carry)

* parity
the parity flag indicates if the number of set bits is odd or even in the binary representation of the result of the last operation. It is normally a single bit in a processor status register.

*of -> overflow

flag info tanda prosesor biasa ada di register flag, biasanya misal setelah instruksi cmp maka flagnya disimpen di register flag langsung bisa dites dg instruksi lanjutan, misal: jz atau jnz
