The 8259 is a specialized I/O port chip. It is never used in the interfacing of I/O devices but is only used for controlling the interrupts in a microcomputer.8259 consists of A0 as the only address input pin. Hence for a microprocessor, only two addresses are possible for the 8259 ports. ... Read More

In 8085 Instruction set, and specially in its logical group of instructions, we have AND, OR, XOR, NOT type of instructions. 8085 does not have instructions to perform NAND, NOR, XNOR operations directly. Now let us discuss the instructions to perform AND operations only.To perform ANDing of two numbers, 8085 ... Read More

In 8085 Instruction set, we are having a set of instructions to perform compare operation where we shall compare two operands, and which will affect the status flags values depending on the result of the comparison. In this operation, 8085 imposes the restriction that one of the operands must be ... Read More

In 8085 Instruction set, there are a set of jump instructions, which can transfer program control to a certain memory location. So after these branching mnemonics we shall have to mention 16-bit target address of the location. These jump instructions can be divided into two categories– Unconditional jump instructions andConditional jump ... Read More

In 8085 Instruction set, we are having one mnemonic JC a16, which stands for “Jump if Carry” and “a16” stands for any 16-bit address. This instruction is used to jump to the address a16 as provided in the instruction. But as it is a conditional jump so it will happen ... Read More

In 8085 Instruction set, we are having one mnemonic JM a16, which stands for “Jump if Minus” and “a16” stands for any 16-bit address. This instruction is used to jump to the address a16 as provided in the instruction. But as it is a conditional jump so it will happen ... Read More

In 8085 Instruction set, CC is a mnemonic, which stands for “Call if Carry”. This instruction is used to branch to the subroutine whose 16-bit address is provided in the instruction, only if Cy flag value is 1. If Cy flag value is 0, program flow continues in the main ... Read More

In 8085 Instruction set, CPE is a mnemonic, which stands for “Call if Parity Even”. This instruction is a used to branch to the subroutine whose 16-bit address is provided in the instruction, only if the P flag value is 1. If the P flag value is 0, program flow ... Read More
