Operations on SFR byte address 208 or bit addresses 209-215 (that is, the PSW or bits in the PSW) also affect flag settings. The term can refer to all possible instructions for a CPU or a subset of instructions to enhance its performance in certain situations. The instruction set or the instruction set architecture (ISA) is the set of basic instructions that a processor understands. 1 Objectives: The ARM Cortex-M4 processor executes a set of 16 and 32 bit instructions, called. The software interrupt is initiated by the main program, but the hardware interrupt is initiated by an external device. Memory-mapped I/O is preferred in x86-based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or Explain briefly the flag register in the 8085 microprocessor. This is the function al Block Diagram of 8085 Microprocessor. The format of a typical instruction is composed of two parts: an operation code or op-code and an operand. Jun 26, 2013 A detailed ppt on 8085 microprocessor instructions. Logic - AND, OR, XOR and rotate. At T2 state microprocessor uses read signal and make data ready from that memory location to read opcode from memory and at the same time program counter increments by 1 and points next instruction to be fetched. Doc. The 8085 has different instructions for accessing main memory and I/O 'memory'. Each instruction has two parts: one is task to be performed, called the operation code (opcode), and the second is the data to be operated on, called the operand. – The 8085 uses a total of 246 bit patterns to form its instruction set. Power supply and frequency. Its clock speed is about 3 MHz. Based on the design of the ALU and decoding unit, the microprocessor manufacturer provides instruction set for every microprocessor.

MVI B, 09 :"Initialize counter" START :"LXI H If the value of the low-order 4-bits in the accumulator is greater than 9 or if AC flag is set, the instruction adds 6 to the low-order four bits. Instruction and data formats. The 8085 microprocessor had four additional interrupts. Easy view of flag contents. INSTRUCTION SET AND EXECUTION IN 8085. For example, the STC (set carry flag) instruction deals only with the carry flag, the DAA (decimal adjust accumulator) instruction deals with the accumulator. Issuing reset causes the processor to fetch the first instruction from the memory FFFF:0000h.
