8086/8088 Pin assignments & functions • AD15 - AD0 –Multiplexed address/data bus –lines carry address bits A15 - A0 whenever ALE (Address Latch Enable) is logic 1 –lines carry data bits D15 - D0 whenever ALE is logic 0 –Note: 8088 only multiplexes D7 - D0 because it uses an 8-bit data bus • A19/S6 - A16/S3 –multiplexed address
Part 8: 8086 Microprocessor PIN Configuration and Instruction Set
Pin Diagram of 8086 and Pin description of 8086 Figure (1) shows the Pin diagram of 8086 The 8086 can be configured to work in either of two modes: ? The minimum mode is selected by applying logic 1 to the MN / MX input It is typically used for smaller single microprocessor systems ? The maximum mode is selected by
Systems Design & Programming 8086 Chipset CMPE 310
The 8086 samples the RESET pin on the rising edge Correct reset timing requires that the RESET input to the microproc essor becomes a logic 1 NO LATER than 4 clocks after power up and stay high for at least 50µs
8086 Pins & Functions - Beam's Pathsala
8086 Pin Functions(Common Pins) Power supply •It uses 5V DC supply at V CC pin 40 and uses ground at V SS pin 1 and 20 for its operation Clock signal •Clock signal is provided through Pin-19 It provides timing to the processor for operations •In microprocessor a time to fetch and execute an entire instruction
Lecture 1-ST-8086
When this read signal pin is at logic 0 the data bus is receptive to data from memory or I/O devices READY: This pin is used to enforce a waiting state READY pin at 0 – the microprocessor goes into idle state READY pin at 1 – the microprocessor does normal operation

What are the pins of 8086?
- The description of the pins of 8086 is as follows: AD0-AD15 (Address Data Bus): Bidirectional address/data lines. These are low order address bus. They are multiplexed with data. When these lines are used to transmit memory address, the symbol A is used instead of AD, for example, A0- A15. A16 – A19 (Output): High order address lines.
What are logical instructions in 8086 microprocessor?
- We can say that these instructions are logical instructions. In 8086, the destination register may or may not the Accumulator. Let us see the logical instructions of 8086 microprocessor. Here the D, S and C are destination and source and count respectively. D, S and C can be either register, data or memory address.
What is the minimum mode of 8086?
- In a multiprocessor system 8086 operates in the Maximum mode . In this minimum mode of operation, the pin MN/MX is connected to 5V D.C. supply i.e. MN/MX = VCC. The description about the pins from 24 to 31 for the minimum mode is as follows:
What is hardware interrupt in 8086?
- The interrupts initiated by external hardware by sending an appropriate signal to the interrupt pin of the processor is called hardware interrupt. The 8086 processor has two interrupt pins INTR and NMI. The interrupts initiated by applying appropriate signal to these pins are called hardware interrupts of 8086.
