reduction 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 counter is now returned to the normal 24−stages in
series configuration. One more pulse is entered into In
which will cause the counter to ripple from an all “1” state
to an all “0” state.

Counter is in three 8 stage sections in parallel mode.
First “1” to “0” transition of clock.
255 “1” to “0” transitions are clocked in the counter.
The 255 “1” to “0” transition.
Counter converted back to 24 stages in series mode.
Set and Reset must be connected together and simultaneously
go from “1” to “0”.
In
Counter Ripples from an all “1” state to an all “0” state.
