8.5.3 Clock/Clock-Pulse Generator
This subsection describes how to program a clock-pulse generator.
Example: A clock-pulse generator can be implemented using a self-clocking timer that is followed
in the circuit by a binary scaler. Flag F 2.0 restarts timer T 7 each time it runs down,
i.e., flag F 2.0 is “1” for one cycle each time the timer runs down. The pulses of flag
F 2.0 applied to the binary scaler result in a pulse train with pulse duty factor 1:1 at
output Q 1.0. The period of this pulse train is twice as long as the time value of the
self-clocking timer.
