Hello @Ganapathi_NASH_INDIA @Kavin_raj_mbd
Based on the topics you are interested in, I would like to point you to the following article series, that describes how to use the DIO, UART, FreeMASTER, ADC, PWM and CAN functionalities inside MBDT for S32K3. Each of the articles provides a detailed description of the necessary steps required to configure and use such peripherals/features, including also application examples that you could try for getting more familiar with the workflow MBDT proposes.

Moreover, please note, that inside our toolbox (latest version is MBDT for S32K3 v1.4.0), you can find various examples demonstrating the operating modes of all the peripherals we provide support for, and of all the functionalities our toolbox enables. You can find these examples, together with help files, and configuration projects, that you could use as starting points for your project development, inside the following path: <toolbox_root>/S32K3_Examples.
Besides this, on our MBDT Community, you have also access to various webinars and videos describing the workflow proposed by our toolbox for applications development. You might find those useful as well.
Furthermore, as you require support for multiple topics related on how to use NXP Software, we would kindly ask you if you could open a support ticket on nxp.com, from the Support Tickets tab.

I would also like to let you know that the majority of the MBDT Community answers are posted by our team of MBDT engineers, and we are providing this support on a best-effort basis, as we are mainly focused on the toolbox development tasks.
By submitting such a ticket, you could get support from teams specialized on such activities, on multiple topics that you are interested in, not only MBDT usage, which I think might help you and your team with the development activities associated to the project you are working on.
Hope this helps,
Irina
