You can stop the timer and start a new one, which in practice will be the same as resetting.

My question is I want to reset timer in UART ISR.

It is possible to reset the timer after start the timer for example i started 5 ms timer and when timer count reaches to 4 ms that time i need to do reset the timer with 5 ms count.

This was very difficult to understand. Do you want to have a UART timeout? Please try to explain in another way.

No actually in UART ISR i am receiving one packet and for checking the end of packet i want a delay of 5 ms. while i am receiving the packet i want to reset the timer count so when there is nothing in the UART ISR that time only i want to start the timer or in other words that timer count will start from 0 to 5ms and in the timer handler i will know that packet is received.

Start the timer with timeout of 90. When it goes off, decide whether you want 10 more or 100 more. Or do you have some event before the timeout that tells you you want to increase the timer? If so, then you can save the time when you start the timer, and when the event occurs, stop the timer and do math on nowTime - savedTime to calculate the new timeout.

Yes i am asking.

I want it without stopping the timer because i want to increased the timer tick before timer timeout. for example i started timer with 100 ms and when its reaches to 90 ms i want to add another 100 ms delay so timer interval will be 190 ms.

Are you asking how to do it? Have you tried stopping the timer and creating a new one?
