In this chapter, you will learn
l
The differences between 8086 and 8088.
l
The pin functions of 8086 in the minimum
and maximum modes.
l
The use of address latches and data buffers
in an 8086 based system.
l
The concept of machine cycles and the
associated bus timings of 8086.
l
The reason for using the bus controller IC
in a maximum mode system.
l
How an 8086 is used in the maximum
mode.
l
To calculate instruction timing and thus
create delay loops.

We have so far dealt exclusively with the programming aspects of 8086. It is now time
to take a look into the hardware aspects of the processor.
