3. Pulse width measurement
While keeping the 16-bit up counter UC8 counting (Free running) with the
internal clock input, the external pulse is input via the TI8 pin. Then the
capture function is used to load the UC8 values into CAP8 and CAP9 on the
rising edge and falling edge of the external trigger pulse respectively. The
interrupt INT8 occurs at the falling edge of TI8.

Measurement” in Figure 3.8.26.
Note: External interrupt INT8 occurs at the falling edge of the TI8 pin input only
This mode allows measurement of the H level width of an external pulse.
The pulse width is obtained from the difference between the values of CAP8
For example, if the internal clock is 0.8 µs and the difference between CAP8
When measuring the pulse width which exceeds the maximum counting
The width of the L level can be measured from the difference between the
