What are the status signals in 8086?
8086 does not directly provide all the signals that are required to control the memory, I/O and interrupt interfaces. Specially the WR, M/IO, DT/R, DEN, ALE and INTA, signals are no longer produced by the 8086. Instead it outputs three status signals S0, S1, S2 prior to the initiation of each bus cycle.What are the status signals in 8086 in maximum mode?
Maximum Mode 8086 System
In the maximum mode, the 8086 is operated by strapping the MN/MX pin to ground. In this mode, the processor derives the status signal S2, S1, S0. Another chip called bus controller derives the control signal using this status information.What is S0 S1 and S2 in 8086?
S0, S1, S2
These are the status signals that provide the status of operation, which is used by the Bus Controller 8288 to generate memory & I/O control signals. These are available at pin 26, 27, and 28.- It is used to write the data into the memory or the output device depending on the status of M/IO signal. It stands for Hold Acknowledgement signal and is available at pin 30. This signal acknowledges the HOLD signal.
