This is an application example where the count values that have been captured at the valid edges of separate
capture trigger signals are stored in separate capture registers in the free-running timer mode.
The count value is captured to CR01n when the valid edge of the TI00n pin input is detected and to CR00n when
the valid edge of the TI01n pin input is detected.
