Pulse Width Measurement
In Pulse Width Measurement the counter uses the internal time base to measure the pulse width of the sig-
nal 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.
