Functional Description
36.4.24.4 Period Measurement
If the channels (n) and (n+1) are configured to capture consecutive edges of the same
polarity, then the period of the channel (n) input signal is measured. If both channels (n)
and (n+1) are configured to capture rising edges (ELS(n)B:ELS(n)A = 0:1 and ELS(n
+1)B:ELS(n+1)A = 0:1), then the period between two consecutive rising edges is
measured. If both channels (n) and (n+1) are configured to capture falling edges
(ELS(n)B:ELS(n)A = 1:0 and ELS(n+1)B:ELS(n+1)A = 1:0), then the period between
two consecutive falling edges is measured.
The period measurement can be made in one-shot capture mode
Mode) or continuous capture mode
