Pulse width measurement without input capture

Busy loop sampling will add delay.

Note that it is often possible to use a single timer for more than one thing. So a free-running timer can be concurrently used for:
1) Software delays where the free-running timer is polled.
2) Capture to measure external signals
3) Periodic interrupts, by having the ISR constantly updating the match register(s)

Yes this i want to try. if you see datasheet of RX610 then Timer unit0 having different functionality.

If i wanna use unit0 channel0,then only one counter is their.
So suppose i want to use this timer for internal counter and for input capture.

So if i will modify or reset main counter then it will disturb other other one.

In this case how to handle???
