Advisories
Three types of advisories are used throughout the manual to stress important points or warn of potential
hazards to the user or the system. They are the Note, the Caution, and theWarning. Following is an example
of each type of advisory:
Note: The note is used to present special instruction, or to provide extra information which may
help to simplify the use of the product.
CAUTION!
A Caution is used to alert you to a situation which if ignored may cause injury or
damage equipment.
WARNING!
AWarningisusedtoalertyouofasituationwhichifignoredwillcauseseriousinjury.
Cautions and Warnings are accented with triangular symbols. The exclamation symbol is used in all cautions
and warnings to help alert you to the important instructions. The lightning flash symbol is used on the left
hand side of a caution or a warning if the advisory relates to the presence of voltage which may be of
sufficient magnitude to cause electrical shock.
Use caution when servicing any electrical component. We have tried to identify the areas which may pose
a Caution or Warning condition in this manual; however, ICS Advent does not claim to have covered all
situations which might require the use of a Caution or Warning.
You must refer to the documentation for any component you install into a computer system to ensure proper
precautions and procedures are followed.

Description
The state of all inputs can be monitored and, if any one or more bits change state, a latched
interrupt request can be generated. Thus, it is not necessary to use software to continuously poll
the inputs to detect achange of state. The change-of-state interrupt is enabled by a software write
to an interrupt-enable register. Six bits in that register each control an eight-input port at one of
two type 8255-5 Programmable Peripheral Interface chips. The change-of-state interrupt latch can
be cleared by a software write.
