3.2.1.4 Period Time Measurement
In Period Time Measurement the counter uses the internal time base to measure the period time of the signal
present on
Counter Source
. The counter counts the rising edges of the internal time base which occurs
between two rising edges on
Counter Source
. At the completion of the period interval the counter value is
stored in a register and the counter starts counting from zero. At every
Sample Clock
(
1
,
2
, …,
6
) the regis-
ter value is read out.
Figure 15 shows a Period Time Measurement.

3.2.1.5 Pulse Width Measurement
In Pulse Width Measurement the counter uses the internal time base to measure the pulse width of the
signal present on
Counter Source
. The counter counts the rising edges of the internal time base after a rising
edge occurs on counter source. At the falling edge on
Counter Source
the counter value is stored in a reg-
ister and the counter is set to zero. With the next rising edge on
Counter Source
the counter starts counting
again. At every
Sample Clock
(
1
,
2
, …,
6
) the register value is read out.
Figure 16 shows a pulse width measurement.
