• In this mode, the microprocessor chip itself gives out all the control signals.
• This is a single processor mode.
• The remaining components in the system are latches, trans receivers, clock generator, memory or I/O devices.
• This system has three address latches and two octal data buffers for the complete 20-bit address and 16 bit data Separation.
• The latches are used for separating the valid address from the multiplexed address/data signals and the controlled by the ALE signal generated by 8086.
• Transceivers are the bi-directional buffers. They are required to separate the valid data from the time multiplexed address/data signal. This is controlled by two signals, DEN & DT/R (low).
• DT/R (low) indicates that the direction of data, iei.e. from or to the indicator.
• DEN signal indicates the valid data is available on the data bus.
• This system contains memory for the monitor and users program storage. It also contains I/O devices to communicate with the processor.
• The clock generator in the system is used to generate the clock and to synchronize some external signals with the system clock.
• The minimum mode system organization is,
