(b) Pulse width measurement with capture register
When pulse width measurement is performed with the TT0CCRn register used as a capture register,
software processing is necessary for reading the capture register each time the INTTT0CCn signal has
been detected and for calculating an interval.
When executing pulse width measurement in the free-running timer mode, two pulse widths can be
measured with one channel.
To measure a pulse width, the pulse width can be calculated by reading the value of the TT0CCRn register
in synchronization with the INTTT0CCn signal, and calculating the difference between the read value and
the previously read value.
