Instant (Software-Timed) Frequency Measurement
With instant frequency measurement, the software controls the rate and time of read-
ing frequency value, which is thus also called software-timed frequency measure-
ment. Whenever the software sends a read command, the current value of the
frequency is returned as shown in Figure 3. 9.

The advantage of instant frequency measurement is low latency. It is typically used
for reading a single sample of frequency value.
3.3.3 Pulse Width Measurement
In pulse width measurement mode, both the high period and the low period of the
counter clock signal are measured. The measured values are updated when a pulse
is completed. This is shown in Figure 3. 10.
