WebJul 30, 2024 · In 8085 microprocessor, the flags register can have a total of eight flags. Thus a flag can be represented by 1 bit of information. But only five flags are implemented in 8085. And they are: Carry flag (Cy), Auxiliary carry flag (AC), Sign flag (S), Parity flag (P), and Zero flag (Z). WebApr 14, 2024 · In this post, we will discuss Vectored Interrupt and Non-Vectored Interrupt in 8085. The Intel 8085 has five interrupt inputs namely TRAP, RST 7.5, RST 6.5, RST 5.5, and INTR. When any of these interrupt pins except INTR is active, the internal control circuit of the processor produces a call to a predetermined memory location.
