9.2 Input Capture
9-4
SYSTEM
CLOCK
The input capture function records the time an external event occurs by latching the
value of the free-running counter when a selected edge is detected at the associated
timer input pin. Software can store latched values and use them to compute the peri-
odicity and duration of events. For example, by storing the times of successive edges
of an incoming signal, software can determine the period and pulse width of a signal.
To measure period, two successive edges of the same polarity are captured. To mea-
sure pulse width, two alternate polarity edges are captured.
