Pulse period measurement
The pulse period of a signal can be measured in the pulse width measurement mode, when the
edge detection of one of the inputs TIPn0 and TIPn1 is set either to “rising edge” or “falling edge”.
The detection of the other input should be set to “no edge detection”.
By detection of the specified edge the resulting value is captured in the corresponding capture
register (TPnCCR0 or TPnCCR1), and the timer is cleared and restarts counting.
Figure 9-33:
Flowchart of Pulse Period Measurement
Note:
External pulse input is possible for both TIPn0 and TIPn1, but only one should be selected for
the pulse period measurement.
Specify either “rising edge” or “falling edge” for edge detection. Specify the edge of the external
input pulse that is not used as “no edge detection”.
Remark:
n = 0 to 7
m = 0, 1
