Define State Trigger Terms "a" through "d"
In the following exercises, you will set up the analyzer to check for and store
a complex sequence of states before it triggers. While the analyzer checks
for these states, it will store only selected states that you define. As in
chapter 3, you will define your trigger terms first, then use these terms to
define a sequence of events. In this case, the sequence will be made up of
states of the ripple counter on the training board. You can use this same
method to monitor any state sequence, such as subroutine calls or read and
write cycles of a microprocessor.
