Figure 13: Connecting Counter/Timer Signals for an Event Counting Operation

Without Using a Gate

Connecting Signals for Frequency Measurement

One way to measure frequency is to connect a pulse of a known duration to the Counter 0
Gate signal, as shown in

Figure 14

. In this case, the frequency of the Counter 0 In signal is the

number of counts divided by the period of the signal connected to the Counter 0 Gate input.
