FUNCTIONAL TEST SEQUENCE
Test function (Figure 8) has been included for the reduc-
tion of test time required to exercise all 24 counter stages.
This test function divides the counter into three 8–stage
sections and 255 counts are loaded in each of the 8–stage
sections in parallel. All flip–flops are now at a “1”. The count-
er is now returned to the normal 24–stages in series configu-
ration. One more pulse is entered into In1 which will cause
the counter to ripple from an all “1” state to an all “0” state.
