(b) Pulse width measurement with capture register
When pulse width measurement is performed with the TPnCCRm register used as a capture register, software
processing is necessary for reading the capture register each time the INTTPnCCm 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 TPnCCRm register in
synchronization with the INTTPnCCm signal, and calculating the difference between the read value and the
previously read value.
