3.3.5 Timer/Pulse
In timer/pulse mode, continuous pulses with specified frequency are generated at
counter output terminal, and an interrupt is also generated with each pulse as shown
in Figure 3. 13.
Figure 3.13 Pulse output and timer interrupt
The output can be gated. If counter gate is in active level, pulses are output normally.
On the other hand, if counter gate is in inactive level, output is disabled. Figure 3. 14
shows an example of active high gate.

Static (Software-Timed) Timer/Pulse
With static timer/pulse, the software controls the time of updating output pulse fre-
quency, which is thus also called software-timed timer/pulse. Whenever the software
sends an update command, the frequency of output pulse is updated to the specified
value after current pulse is completed as shown in Figure 3. 15.
