Hello Gaurav,
I would like to recommend you to the document Software for S12ZVM motor control kits
There can be found the download links, Quick Start Guide, S12ZVM motor control kits, and application notes.
After running .exe file, the folder where example code is located will be created on the path C:\NXP\MC_DevKits\MTRCKTSBNZVM128\sw.
There can be found the project MTRCKTSBNZVM128_SENSORLESS_CW10.
Unfortunately, I'm not familiar with MCUs from point 2 and 3. However, you can specify your requirements for the MCU and I can recommend you the concrete MCUs.
I hope it helps you.
Best Regards,
Diana
