Hello @Vijay_Vj 

1)There are some basic demos about timer, counter under SDK, for example "ctimer_match_example".

Download SDK from:

https://mcuxpresso.nxp.com/en/select  

2) Also you can use MCUXpresso configure tool to config refer to your requirements:

Hello @Vijay_Vj 

Sorry there isn't an example code exactly for your application.

Recommend you refer to user manual of chip and SDK demo to development.

Hello @Vijay_Vj 

You can consider below steps:

1） Define a global variable cn.

2) Enable plus pin interrupt, in the interrupt, cn+1;

3)Configure timer, read the value of "cn" in each seconds interrupt.

Just a simple suggestion.
