Timing diagram of 8086 microprocessor in minimum mode

In my previous post, I have explained  8086 microprocessor in minimum mode. This post explains the timing diagram of 8086 microprocessor in Minimum mode.

1. READ CYCLE TIMING DIAGRAM 

The read cycle begins in T1 with the assertion of ALE (Address latch enable ) and M/IO signal for memory or input-output process. During the negative going edge of the signal ,the valid address is latched on the local bus. The BHE or bus high enable and Ao signal addresses low , high or both bytes.

2. WRITE CYCLE TIMING DIAGRAM.

8086 microprocessor in minimum mode

Minimum mode in 8086 microprocessor :-
Microprocessor 8086 is operated in Minimum mode by strapping its MN/MX pin to logic 1.In this mode, all the control signals are given out by the microprocessor chip itself . There is a single microprocessor in the minimum mode system.
The figure below shows the microproceesor 8086 in minimum mode. The block digram shows various components in the systems like latches,transceivers,clock generator or i/o devices.
The latches that are used to separate the valid address from the multiplexed address are generally buffered utput D-type flip-flop,like 74lS373 . The latches are controlled by ALE. Transreceivers are bidirectional buffers and sometimes they are called data amplifiers.
DT/R indicates the direction of data. T means transfer in case of write and R means receiving data in case of write cycle.
20 address lines and 16 data lines is clearly shown in the figure below.

The working of the minimum mode in next post.
