The interrupt requests are accepted by 8259 from many interrupting devices IR0 to IR7  pins. After that, it identifies the highest priority interrupt request from those inputs that are already active. To configure the 8259 for fixed priority mode of operation, among them IR0 has the highest and IR7 has ... 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 XOR operations only.To perform XORing of two numbers, 8085 ... Read More

In 8085 Instruction set, there a set of instructions which can Accumulator contents left orright. It is to be noted here that rotate operation can be performedonly on Accumulator contents. These instructions set is listed below– Mnemonics, OperandOpcode(in HEX)BytesRAL171RAR1F1RLC071RRC0F1Mnemonic RLC stands for “Rotate Left Accumulator”. It rotates the Accumulator contents to ...

In 8085 Instruction set, there are a set of jump instructions, which can transfer programcontrol to a certain memory location. So after these branchingmnemonics we shall have to mention 16-bit target address of thelocation. These jump instructions can be divided into two categories– Unconditional jump instructions andConditional jump instructionsHere in this ... Read More

In 8085 Instruction set, we are having one mnemonic JPO a16, which stands for “Jump if Parity Odd” 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 ... Read More

Sometimes in 8085assembly language coding, we require to repeat a certain program segment for multiple times. In those situations, we can define sub-routines. In those subroutines, we can enclose our repeatedly reusable Instruction set or code. And then as when required we shall call those sub-routines accordingly. Sub-routines can also ... Read More

In 8085 Instruction set, CNZ is a mnemonic, which stands for “Call if Not Zero”. This instruction is used to branch to the subroutine whose 16-bit address is provided in the instruction, only if the Z flag value is 0. If Z flag value is 1, program flow continues in ... Read More

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