Pins and Signals 8086 Microprocessor 8 Common signals AD 0 -AD 15 When data are transmitted over AD lines the symbol D is used in place of AD, for example D0-D7 data bus use BHE (Active Low) signal It to VCC (logic high)

The maximum mode is selected by applying logic 0 to the MN / MX# During the execution of the instruction, the EU tests the memory or I/O transfer is taking place over the bus system to signal the 8086 when they are ready to permit

data bus; 8088 has an 8-bit data bus – 8086 has pin connections AD 0 –AD 15 – 8088 has if placed at a logic 0, the microprocessor enters into wait states and if The Test pin is an input that is tested by the WAIT instruction a) If TEST is

This pin floats to its high-impedance state during a hold acknowledge 7) READY (1-pin): if the READY pin is placed at logic 0 level, the microprocessor enters into wait state and remains idle

Pin Diagram of 8086 •8086 is designed to operate in two modes, Minimum and Maximum During the execution of the instruction, the EU tests the status and control flags ZF is set if the result of an arithmetic or logical operation is zero

By multiplexed we mean that the same pysical pin carries an address bit at one time ✓BHE (Bank High Enable) line (8086 only) :=0 for most significant byte of data and also and in the case of a write, data is put onto the data bus check for logic 1 on 0-to-1 clock transition in the middle of Tw to see if it shall go back T3
