24.2 Measuring Time
Time measurements on the pulse width can be similarly
performed using the A/D module’s internal capacitor
(CAD) and a precision resistor for current calibration.
Figure 24-2 displays the external connections used for
time measurements, and how the CTMU and A/D
modules are related in this application. This example
also shows both edge events coming from the external
CTEDx pins, but other configurations using internal
edge sources are possible.
